9800GT +Pentium D or HD 4670 +Athlon64 x2

Need help guys,

I plan to buy a new vga card, my old system are Pentium D 820 and Asrock 775 DUal VSTA. Since the mobo only supported 4x PCI-e (am i right?) im gonna need a new mobo (PCI-e 16x).

Another problem, bcoz i have to change mobo anyway im looking around and read that Athlon64 x2 easily beat Pentium D and very cheap too (type 4800 +/- $50)

So for my tight budget, what should i pick:

a) Keep my Pentium D, buy a LGA775 mobo (ASUS P5KPL-AM SE /GIGABYTE GA-G31M-S2L) and 9800GT (Leadtek)

b) Buy Athlon64 x2 4800, an AM2 mobo (ASROCK N68-S) and HD 4670 (Sapphire)

I think both options are still on the same price range

Note: i only have 400Watt PSU (Silverstone ST400), 2GB DDR II 667

Any suggestion? many thanks.

both are sad sad ways to get decent gaming, but reguardless, the facts are:

Pentium D (as long as its a ~3ghz model, not the 805) + 9800GT = good at high res
Athlon64 x2 + 4670 = overall better for general gaming (better minimum benchmarks)

that Pentium D is what feeds the video card - the athlon starves it *less*

Hold it right there the X4 slot isn't as much of an issue as you think.
You can put a C2D in the board and depending on what you are upgrading from Graphics wise im betting you can get a decent card in there that will increase the performance no end.

These guys http://forum.micromart.co.uk/Topic173777-19-1.aspx (especially Slipstreem) know a thing or two about getting the best from your board. Check out the system specs at the bottom of his post ;)  There's plenty of gas in your board yet ill bet. Just so you know he says the 3870 is restricted by the slot but only slightly. Anything below that will be fine. Trust me he knows what he is talking about.
have a look at the link then either ask over there or post back on here with any questions.

Really PCI-e X4 slot won't be a problem?
I heard that PCI-e X4 won't be a problem for older vga card but will be huge blow for newer card.
I can accept if it is only <10% vga card performance loss, then i'll keep this mobo and go for HD 4850 or 9800GT

You do make me sad :) 

it is Pentium D 820 (2.8 ghz) but overclocked to 3.1 ghz

So are u saying that Pentium D 3ghz (o.c) with a 9800GT in PCI-e 4x mobo is ok for gaming?

let say Crysis 1280X1024 2xAA high quality? not to forget my 400watt psu
June 15, 2009 11:08:04 AM

why dont you try an E5200 overclock it to 3-3.5 Ghz and buy a 9800 GT or a GTS 250 and get the most of your money???

Ati cards use the bandwidth a lot better than Nvidia cards do last i checked, if it was me i would go with the 4670. The CPU really needs updating whatever you decide to do. Its going to hold most cards back. You have a 775 socket so the choice of cheap overclockable CPU's is pretty vast.
Do check your Bios edition for compatability though. The Asrock 775 DUal VSTA will support a loy of differant hardware as long as you have the correct Bios, this isi especially true for the GPU's

I dont think this mobo support 45nm cpu ... i about sure it dont.
E5200+G31+hd4850+psu ... well im about to tell you to buy a new computer ...

The best would be to buy a cheap HD3850 or HD3870 ( can be found way under 100$ ). Or HD4670-9600gt.

What resolution are you gaming at? One way i believe will ease the bottleneck on the pcie is to increase the frequency.

Looks like the Pentium D 820 has to be concerned more than the pci-e 4x mobo...
I believe adding 4670 wont be compatible with my default bios, need to flash it
but since ive never done it, i doubt my mobo will survive thereafter :na: 

As u said, i'll go with 4670

thanks mac :)

use to play in 1280*1024

increase the freq..u mean OC'ing the graphic card?
is there any exact percentage number how should i increase the core &memory clock gpu card in pci-e 4x, so it will give the same performance like if it used in PCI-e 16x?

I would check if i were you before buying the 4670 as i said The Asrock 775 DUal VSTA will support a lot of differant hardware as long as you have the correct Bios, this isi especially true for the GPU's.
So you may well need to flash the bios in any case for the 4670 to be compatable.
If you are not happy doing this sort of thing then a new cheap Mobo may be the safer option for you.

Thanks, youve been helping much :) 

I've been wandering around and it seems quite much ppl who use the same mobo as mine with the latest gpu card, because i always thinking it'll be waste of money using a good gpu card if only get 50% from their full potential (i never got the exact number how much it'll be bottlenecked in 4x PCI-e).
But considering those people maybe im worried too much. Then i checked to ASRock and an 4670 or 4770 is not enlisted in this mobo supported vga, where i can find this correct bios? (and i really hope it came with manual how i should flashed it :??:  )

The Asrock site should tell you which utility to use to flash the Bios, The best place for getting a Bios is here http://www.pctreiber.net/filebase.php?cat=22
Most of the Guys over on the MicroMart site i linked you to earlier use these Bios's
If you go to the Asrock site and find your board it will then have a red + sign on a white flag which is a link to tell you how to flash the bios.

Im not sure but i think this is your board ? Please check as it must be correct or it wont work and could hurt your PC http://www.asrock.com/mb/download.asp?Model=775Dual-VST...

In my opinion i would go with with the 9800gt.
In your bios there is a setting called pcie (bus) frequency 100mhz. You can up that to maybe to 110-115mhz it should help the pcie x4 a little.

Yes that is exactly mine,
I've searched ASRock site but im afraid i didnt find any clue what bios should i use for 4670 or 4770
from Micromart site, i read this guy using 3.17a for 4670, but i doubt i can just rely on that...
also i dont hv any floppy drive, since a floppy disk for bootable system required in bios flashing, i just can use a CD rite? (sorry for being noob :(  )

Between those 2 options, go with the 4800+ and the 4670. Look, I've got a 5200+ and it's not bad with my 9600gt. Do this, go with an AM2+ mobo that will support phenom II chips, which it appears the ASROCK will, get your 4670 and 4800+, OC the processor for extra performance, then down the road when you can spend more, grab a better video card, and maybe a phenom II chip, along with better memory. If you do it this way, then you are going to a path you can upgrade out out of without doing a full rebuild later. Because otherwise what's the point b/c LGA 775 is a dying socket, no sense in upgrading to dead end tech. Been there done that.

go for athlon and 9600gt
your graphic card wont be fully used by processor if you chose first option
yet,the athlon x2 with 9600gt is best option:)

Just remember that there are risks and you do this at your own risk. I have flashed my Bios before but straight from a downloaded file and it went well. It can occasionally end up badly.

Good luck

Sorry to threadjack, but should I be worried about having a Pentium D (3.0GHz) and am planning on getting a 9800GT? Will there be any bottleneck?
June 20, 2009 11:33:02 PM

the pentium d is essentually 2 p4 on one die and the amd performes better as a dual core but you can get a core 2 duo for pretty decent like
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
or amd like this
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
there is even triple core processors like these
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

the ati drivers a a little buggy but the 9800 may not have the brawn the ati has but it works smarter like indepentently adapting its cores ( forgot the right word)

I saw someone put the idea for the 9600 gt. The 4670 should be about the same performance as the 9600gt. However, the 9600gt is supposed to have a higher power draw. That being the case, and not knowing what PSU the op is running, I'd reccomend the 4670. To whoever is asking about a 9800gt, check your PSU to be sure it can actually run this card.
