Graphic card for 1024*768

the ammount of memory would not make a difference at that resolution. anything with more than 512mb will perform the same provided they are the same card.

you'd be good off with a gtx 460 or a radeon 6850.

2gb is too much, though a 560ti and 6950 would fit your budget perfectly, they would be complete overkill because of your resolution.

Here you go, I can see going overboard so ill comply

2GB 0_0 That would be overkill for even 1080p! I mean save money for something more useful man...

Get 6770 and it's enough

And This PSU (I know CX430 is enough but you ask for 600W so yeah)

If you are looking for monitor I found one on good price:

After you can buy the same PSU that I suggested and get this
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

EDIT: I found a weird 6450 which has 2GB, http://www.newegg.com/Product/Product.aspx?Item=N82E168... Is it a wrong writing or what?

I agree with refillable, an HD6770 is the most you should consider for such a low resolution. Anything better is pointless.

at your resolution, games are cpu bound. if you have a system that allows cpu overclocking, then overclock your cpu.
as for gfx card, 6770 (as long as your psu can run it). you can get a higher end one if you upgrade display/raise gaming resolution in the future. with a psu that can power it - a radeon hd 6870 1 gb gddr5 or geforce gtx 560 ti 1 gb gddr5.

a 6670 has considerably lower power requirements and also draws all it's power straight over the PCI port, so no PCIE power cables from your PSU required.

I also agree with refillable; and that you don't need a 600W PSU for a HD6770 or even a HD6870.
With a $300 budget, I'd probably do something like this:

Acer S200HLAbd Black 20" 5ms LED Backlight Widescreen LCD Monitor
Model #:ET.DS0HP.A01
Item #:N82E16824009317
$139.99 -$40.00 Instant $99.99
This monitor is 1600x900. I recently got the 1920x1080 version of this monitor (with the LED backlighting) and I really like how nice it looks. I think the $10 over a non-LED version is worthwhile. I didn't go for the full 1080p to keep GPU requirements consistent with your budget.

Antec EarthWatts EA-500D Green 500W ATX12V v2.3 / EPS12V 80 PLUS BRONZE Certified Active PFC Power Supply
Model #:EA-500D Green
Item #:N82E16817371035

$89.99 -$32.00 Instant $57.99
There's a rebate on this too. The Earthwatts PSUs are very solid, and also quiet. This is a good deal on the $500W version.

HIS IceQ X Turbo H679QNT1G2M Radeon HD 6790 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card ...
Model #:H679QNT1G2M
Item #:N82E16814161371
Mail in Rebate Card
$149.99 -$10.00 Instant $139.99
The HD6790 has a 256bit memory path, so it is actually a visible step up from the 128bit HD6770. There's a rebate on this one too, if you play that game (and win).

Subtotal: 297.97

If you can stretch your budget another $10, you can get a HD6850; there's a HD6870 at that price too, but I wouldn't get that one. Although I normally like HIS, the comments seemed to indicate possible quality issues.

Edit: There were a couple of cheaper options iirc, but the ones I chose also had free shipping.
If you have no desire to replace your monitor (seriously, you'll wonder why you didn't when you finally do), then a HD6670 is likely all you need, and as stuffe said, doesn't need auxiliary power. Any good 300W PSU can run it.

but man will this work on intel dh55pj mobo and also i was thinking of buying 4gb dr3 ram

but man games like gta need resource memoryfor higher graphics.

hey can i buy gtx 550 ti 2gb

if you don't believe me then go ahead but that card is horrible.

and the 2 gb doesn't do anything.

gta 4 will not use it and niether will any game.

the 550 ti is worse than a 460

can gtx 550 ti 2gb work on intel dh55pj mobo with 2gb ddr3 ram and what psu do i need.i want to play all latest games and upcoming games of 2012 at max settings on 1024*768.also should i increase my ram to 6gb.or should i get radeon 6870.or should i buy gtx 560
my total budget is $250

Can gtx 550 ti 2gb work on intel dh55pj mobo

so which graphic card should i finally buy that can play all 2012 games at max settings at my resolution.and what power supply do i need .now my budget is $200

should i buy gtx 550 ti or radeon hd 6870 or 6790 or gtx 560 ti and will it work on intel dh55pj

With a $200 budget, remove the monitor from my earlier suggestion. Get the decent PSU and HD6790.

Yes.

max settings might not be possible, but you might be able to crank up settings to high.

this one has no cfx support. since you're using a micro atx motherboard with one pcie slot, i figured you didn't need cfx support. make sure this size fits your case and is able to run cool.

With 6790/6770 you can max out games and no Crossfire for you because of the motherboard it's a micro ATX. Anything better than those GPu will be completely waste in your resolution. If you are planning to get a new monitor then get 560 ti. You also buy PSU and 4GB RAM. Then you can enjoy...

so which one should i buy.or just put it this way which is the best gpu for money out there in the market is it gtx 560 ti 2gb or radeon hd 6950 2gb

NO 2GB AND DON'T WASTE YOUR MONEY!! (sorry for caps because this is really important)

Let me repeat. At that resolution, anything higher than 6790 1GB Is pointless and waste of money. This is such a small resolution, If you don't plan upgrading the monitor don't buy those 2 cards and buy 6770/6790, new PSU and memory.

under $200 i also want a good power supply and computer case that handles this card

.... didn't you say you want a gfx card and a psu under $200 $300.. now a case too?
what are your running your pc in?
what are your current full specs?
you might be hitting cpu and gpu bottlenecks before you utilize 2 gb vram limit at 1024x768 resolution. unless you're upgrading your display to a 1080p or higher, 2 gb vram might be overkill.

at 1080p nothing even hits 1gb of vram

considering thats more than 2 million pixels

at 1024x768 its just under 800k pixels and will not even get close to using 512 mb let alone 2 gb. even a 1 gb card is overkill.

so you wasting your money paying for the extra memory you will never use.

With a $200 budget, needing case, PSU, and GPU, get these:

CORSAIR Builder Series CX430 V2 (CMPSU-430CXV2) 430W ATX12V v2.3 80 PLUS Certified Active PFC Power Supply

When you get the rebates back, assuming you do, you can order some more RAM.

my specs are:-
core i3
2gb ddr3 ram upgrading to 6gb
intel dh55pj motherboard
500 gb hdd

Buy one CX430 about $50
And buy one 6770 about $125

problem is, the more components you try to cram into your fixed budget, the less powerful gfx card you'll be able to afford. at your res. even a radeon hd 6670 1 gb gddr5, a corsair cx/Antec EarthWatts Green psu, a Xigmatek Asgard II/Rosewill Challenger-U3 case (copied from the dec 2011 sbm builds  ) will do. make sure your existing components fit together.
make up your mind about your max budget, what components you want to upgrade and how much you're willing to spend for each.

pls tell me the best graphic card for less than $175 that can play all future 2012,13 games max at my resolutionan it is well reputed.
on psu i'm not spending more than $45
and on case....hmmmm i'm not sure which one to buythat can suit my specs and gfx and psu

Decent GPU: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Decent PSU below $45: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Best card below $175 is the HD6870 but as others are saying for 1024x768 it is simply a waste of money. Just get an HD6770, it is all you need.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
You should also get 2 more GB of ram, not 4gb. 6gb doesn't make sense on a dual channel motherboard. You can go for 8gb but it's not really necessary. FYI if you are using a 32-bit version of Windows you literally cannot use more than 4gb.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
For the PSU this is cheap and fine for your system with an HD6770;
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
This is a very nice case for the money;

The above is $219 shipped, $179 after rebates and you get a free game(Dirt 3) as well as a $15 gift card to newegg. The are all high quality brands and the card has excellent cooling.

Dude, get either a 6770 or 6850, those are the 2 possible cards I can only suggest for someone playing at that resolution. DO NOT GET 2GB CARDS! THAT RESOLUTION WILL SOLEY RELY ON YOUR CPU!

at this point I think this guy is just trolling. We have given him more than enough info and suggestions and he just keeps changing his requirements

i just want to play all latest games at max and this is gonna be my first graphic card.earlier i have always used onboard graphics but in them you can't just have the feeling of playing a game,so that's why i'm taking suggestions from you guys cause you are experts.i need a perfect upgrade and i'm not gonna upgrade my pc in next 4years.so,please help

what if i get a new 20 inch display

Get 6950 2GB as I said before http://www.newegg.com/Product/Product.aspx?Item=N82E168... but then it's a waste and get only 1GB no problem. If you don't mind my suggestion go get 2GB, but single 1080p monitor won't benefit 2GB only 1GB is needed.

Also change your PSU to a decent one.

Do you need a case, or not? Is your budget $300, or $200, or something else? As to "on psu i'm not spending more than $45 ," fortunately we have listed two, the 400W Corsair Builder or the 380W Antec Earthwatts. Either can power the strongest graphics card that makes any sense for your resolution. Before you decide to get a cheaper PSU, go to www.hardwaresecrets.com, www.jonnyguru.com, or www.hardocp.com and read a few of their articles and competent technical reviews of PSUs.
I'm only throwing this out as a reference point, but I tested my mostly older games with a HD6670 at 1920x1080 and found them all nicely playable, most of them maxed. You're going to be playing much more demanding games, but at a less demanding resolution. We are suggesting that a HD6770 is sufficient, and that a HD6870 is an unnecessary waste of money. I have posted suggestions for multiple budgets, and I don't think any of us, whom you kindly call "experts," have substantially disagreed on any of each other's suggestions. You have enough information to make a rational decision, and a lot more questions and answers will only muddy the waters.

Dude you are awesome just look at what I recomended and buy that and iit is under 200 and covers all you concerns if you upgrade your monitor it will be enough to do that as well

so gts 450 or rdeon 6770.which one is better for my resolution

6770!

for your resolution, radeon hd 6770 1 gb gddr5 would be better than a gts 450.
get a good psu to power that 6770.
