The problem with your board is that its AGI("AGP 4/8 compatible") port is more or less 2 PCI slots(The chipset has NO AGP support, but mushing 2 PCI slots works, but the performance hit can be bad). As such the only cards that have been tested are listed on the Asrock site. Other cards "may" work, but there is no way to know for sure.
http://www.asrock.com/mb/vga.asp?Model=775i65gv&s=775&c...
As for memory, The max is 2 gigabytes. 2 x 1gig sticks. The top memory speed supported is DDR PC3200(400mhz)
If you can get a decent card farcry 2 may run at lower end settings, but that would be about it.

Just a little help here...
I'm upgrading my entire system and trying to decide which Graphic Card to go with...
My old system is a has a AMD 64x2 @3800, 2GB Ram, 8800GT 512mb
My new system will be a Intel i7 920, 6GB, and ???? Video card...here is where I need your help.
I currently have a 8800GT 512mb...
I've been very happy with the performance of this card and it has extended the life of my computer...but again...time for a new system.
I am having a custom system built and can have a 9800GT 512mb installed...but no 8800GT. I can go as high as the ATI 4870 card as well...
I read the FAQ where it indicated that you must have 2 of the same videos cards to run SLI...but I also read on THG that the 9800GT 512mb is just a repackaged 8800GT.
My questions are:
1) Can I use an 9800GT in SLI with my 8800GT...?
2) Would 2 x 8800GTs in SLI be better than running 1 x GTX280?
* Seeing as I can purchase a 8800GT 512mb for around $120.00 this could save me quite a bit of $$$
3) Or for that matter...running 3 x 9800GT vs 1 x GTX280 (or better...285)
This has become very confusing to me...
Thank you in advance for any replies.

I think I understood the FAQ, but I wanted to be absolutely sure of this first.
I currently have a Visiontek HD 4850 card running, and I plan on buying a new card soon (preping for Empire: Total War). I was originally planning on buying from Newegg, but they no longer have a Visiontek 4850.
Amazon does appear to have the card, as does Micro Center. However, Newegg also has two cards that, as far as I can tell, are roughly the same clock and memory speed. However, they are from different manufacturers.
What I'm trying to be sure of is whether it's risky to buy from a different manufacturer and run CrossFire, or whether it's a relatively safe (and, as far as I can tell so far) cheaper move.
I also noted that one of the cards that Newegg has uses DDR4 memory instead of DDR3, so I'm wondering if that makes it incompatible.
Any thoughts would be helpful; in the meantime, I'm going to keep looking around for cards...
For the time being, here's some info, if it does any good:
My current video card: http://www.microcenter.com/single_product_results.phtml...
Cards I ran across on Newegg: http://www.newegg.com/Product/Productcompare.aspx?Submi...
They got the idea in my head, but I may find others.

You "Can" crossfire your current card (which has 625MHz Core Clock Speed and GDDR3) with both of those cards in the neweggs link,but i dont recommend it,because:
1_The Appolo card has the same clock/memory speed but its GDDR4 and yours is GDDR3.
2_The HIS one has a little more core clock speed than your current card.
Here are 4 cards which has the same specification of your card and i recommend them to be crossfired with your card:

So then it is relatively risk free to combine different brands? Great! That will make things easier. Thanks for the links, too.

Acht, looking at the cards in comparison brought more questions, not answers
Does the OpenGL matter? One of the cards has OpenGL 2.0 while the others have 2.1. Does that make a large difference? Could I just d/l an update for OpenGL?
And I'm assuming (as I've never heard of it before) that RoHS compliant has to do with this http://en.wikipedia.org/wiki/RoHS and not something else.

I think there is a mistake in newegg,HD 4850 supports Open GL 2.1:
http://ati.amd.com/products/radeonhd4800/specs.html
RoHS,ASUS always advertises about it
its not anything important
(as i said mostly advertising )

Well thank you very much. Now comes the task of figuring out which brand is better. :\
*much later*
I didn't want to make another thread of this, and it is CrossFire related:
I think I've narrowed down my choice of a new card to the HIS 4850 cards.
http://www.newegg.com/Product/Productcompare.aspx?Submi...
What I'm contending with is whether to go with the cheaper fan, or, since I'll be running CrossFire, I should shell out the extra $56 for the cooling of the second one.
In addition, on Amazon and Newegg, I found this card: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
I noticed that it's memory and clock speeds are a bit faster. If I understand correctly, what this will result in is that this card, were I to get it, would slow itself down to match my slower card.
Is that acceptable, considering the better price I'd be getting for the cooling? (and the additional game)

In that case,you will benefit from SLI/CF,you may want to look at dual video cards too like HD 4870X2 or GTX 295,i myself have a HD 4870X2 and i am happy with it.I have some questions:
1) Does CF or SLI helps achieve higher resolutions?
2) Is there much difference in performance between HD4850 DDR4 & HD4850 DDR3?
3) I'm using Athlon64 X2 6000+ processor. Does it bottleneck the processor if i use HD4850 in Single mode/CF mode?
4) Which PSU would be better for HD4850. (PSU1, PSU2,PSU3)

Note from FAQ:
What about brands ?
Well the brand doesnt matter , again for example , you can use a XFX card with a EVGA card , or a SAPPHIRE card with a DIAMOND card , just make sure they have the same memory and same clocks.
What will happend if 2 cards have the same amount of memory but one has higher clocks than the other?
One of the best ways to learn is to make examples.
You have a 8800GT(Normal edition,no OverClocks) and you want to add another 8800GT(Which is OverClocked),then:
1_The OverClocked one will lower its clocks to reach the Non-OverClocked card.
2_You can OverClock your card(The one that has Stock frequencies) and reach the OverClocked card.
Remember, you cant ALWAYS OverClock the normal card to reach the other card,because it may not OverClock that much and may become unstable.
WARNING:There are many exceptions in Computer Hardware, for example "Mousemonkey" a member of this forum has told me that when he puts his ASUS 7900GT card (Which is at stock speeds) with a XFX 7900GT(A OverClocked card) the ASUS one raise its clock to reach the XFX one which is an exception and as i said exceptions are alot in Computer Hardware.
Between those cards as i said go for the one which has the same specifications like your card,If you can afford the model which has better cooling,go for it.

1_No,multiGPU doesn't raise the resolution,resolution depends on the model and specification of your monitor.
2_No
3_Athlon X2 6000 is a good processor and you will be fine when you put a HD 4850 in your system(however in some very intensive CPU games like World in conflict,supreme commander and mostly RTS game,your CPU may bottleneck)
4_All of them have actually same specifications.

Does CF or SLI helps improve gaming in higher resolutions(I mean resolutions like 2560x1600)?
Sorry for my bad English.
And regarding the second question, i still have doubt. As then, what is the purpose of DDR4 memory then.

I understand that getting a card that is faster will result in it lowering its speeds. However, considering that one of the cards I looked at is slightly faster, but cheaper than a card of the same brand line that has the same speed as my card, would it be a bad idea anyway.
Would it cause problems, rather than the card simply slowing itself down? If all the card will do is slow itself down to match my current card, then it seems like a good deal to pay $30 less than the card that has the same specs.

Yes as i talked about it in the FAQ,multiGPU shines at high resolutions like 1920x1200 and higher.
DDR4 is faster than DDR3 but not much(in HD 4850)

Here's the card that matches my current 4850:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Here's the faster, but cheaper card:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
The only differences are that I can see beyond price is that the second one has a core clock speed of 650MHz and a memory speed of 2000MHz, whereas the first card has a core clock of 625MHz and a memory speed of 1986MHz (Micro Center lists my card as having "1000MHz clock, 2000Mhz effective).
Also, I came across this:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
That's what I was going to buy (it's the same as my current card, except with a different cooling system), but they no longer sell it.

The main incentive there is that one of the cards I saw was about $30 cheaper than buying a card from the same brand line, but with the same speed as my card. It may become a non-issue, as that particular card has some unfavorable reviews on Newegg regarding it's workings with 64-bit operating systems.

Thanks in advance for any responses.
I currently have a Asus M3n -HT Deluxe with Phenom 940 BE 4 Gigs of 5-5-5-15 ram just upgraded form an opty 175 and Abit MB, new system walks all over the old one.
Big question now is I have a 8800 GTS 320MB and a 24" I run at 1920x1200 Would go higher if the monitor let me.
From what I have seen a GTX 260 basically walks all over a pair of 8800 320gts in SLI my board is 3-way SLI capable but that seems like not a very good idea. (heat lots of it, power consumption gobs of it, scalablity issues)
So thoughts are get a GTX 260 for about 200 bucks and wait till they drop to about a 100 and grab another one.
The case is an Antec 900 with all fans, the power supply may be an issue. Antec 500W that is 4 years old. I still have my old MB CPU and will build another system with it for my son. Have an old PCI-e card laying around I can stuff on it.

Ok,if so then go for the cheaper one but don't pay alot of attention to newegg reviews,check reviews from tech sites
Of course, I can always use Catalyst to overclock my original card, if I wanted. (and if I understood the FAQ.) After all, it's only 25 MHz and 14 MHz on the CPU and memory, respectively.
Problem I've found with tech sites so far is that none of them talk about problems with Vista....so either they ran into none, or they aren't testing long enough >_>
On the other hand, unless HIS has their own drivers or software with the video card, as opposed to the standard stuff that came with my Visiontek, then I should have no problems, as my Visiontek card has only run into problems when I neglected the drivers.
So the HIS 4850 with the 650MHz clock is looking to be a winner. Something flashy to go with my new mouse and keyboard.

Yes,for 1920x1200 defenitley get another card,8800GTS 320 can not keep up in tha resolution,GTX 260 is good,you may want to look at HD 4870 too.

May get a 260 55nm Newegg has them on sale today! 184 after rebate, kinda hard to beat that. Will add one later on any ideas on the PSU? I am guessing a 750 should be enough for SLI

I have read the first and last page of this thread.
I saw so many errors it got me quite irritated, one in the guide and one in a reply (although that could have already been answered).
the one in the reply was asking about a monitor with a good refresh rate, around 6ms or under.
6ms is the response time of the monitor, not the refresh rate. the refresh rate is measured in hertz, and is generally around 60hz.
the error in the guide was about MultiGPU technology being only for PCI-E graphics cards.
here's a quote from wikipedia that I read a long, long time ago:
"Scan-Line Interleave (SLI) from 3dfx is a method for linking two (or more) video cards or chips together to produce a single output. It is an application of parallel processing for computer graphics, meant to increase the processing power available for graphics. SLI from 3dfx was introduced in 1998 and used in the Voodoo2 line of graphics accelerators. However, the original Voodoo Graphics card and the VSA 100 were also SLI-capable.
Nvidia Corporation reintroduced the SLI acronym in 2004 as Scalable-Link Interface"
3dfx's technology was meant for igp, pci and agp cards. I remember there is a geforce <6 card which is AGP and is SLIable, although not in the same way that we do it today. You used to have a master and a slave card, which used a daisy chain cable to connect from the vga socket on one card, to the other socket on the other card, and then on to the monitor.
so it would look like this

yeah. take that.
I saw so many errors it got me quite irritated, one in the guide and one in a reply (although that could have already been answered).
the one in the reply was asking about a monitor with a good refresh rate, around 6ms or under.
6ms is the response time of the monitor, not the refresh rate. the refresh rate is measured in hertz, and is generally around 60hz.
the error in the guide was about MultiGPU technology being only for PCI-E graphics cards.
here's a quote from wikipedia that I read a long, long time ago:
