Which GPU to buy???

Your PSU is not going to handle anything.

Your RAM and CPU are also going to limit.

You could try going Radeon 6770, but I agree, no guarantee that PSU is going to handle it.

Really if you want to play the "latest games," you need a new system.

i can upgrade my PSU but whats wrong with my system???

On that resolution he could run the latest games with a new GPU. Like a 5750 or something. Most games scale down decent enough for such a computer.

7750

it should work with your PSU, assuming that it is a decent PSU

I agree with geotek 5750/6750 and agree to add more ram. your system is light. even if you're running xp it'll help to have 2-2gig sticks.

for latest games, you could upgrade to a whole new pc. you could save up more and add to your $120 and get a decent pc with current stuff.
with your current specs-

+1.
7750 is currently the most powerful gfx card that does not require an extra pcie power connector. sapphire, his, xfx, asus, msi card will do. cards like 7750, 6770, 6750, 6670 should be enough for 1024x768. keep in mind that at your resolution, games are likely to be more cpu dependent.
add at least 2gb more ram if you can. modern gfx card demand at least 1 gb system ram. you'll need the rest for other tasks.

The DG31PR motherboard has got a PCIe X 16 1.0 slot. That's going to be a little limiting. If it was 1.1, it would have been a bi t better.
You'll have to go for a better PSU. A good 380-400W should be able to handle a good card.
At 1024X768, which is not at all a big resolution, I'd say you get a HD 6750 or a HD 7750, like the other members said.
Best you get a hD 7750, since it is the fastest card that doen't require an external pcie power connector.

^ +1 , 7750 seems like your best option. Doesn't require any power connectors. As long as your PSU is stable, It will run fine.

Wait, wasn't PCI-E x16 OK with 7750? I don't think there is a slot bottleneck at all...

7750 should be fine with PSU above 18A or more in the +12V Rail.

With a 1.0, I'm not sure. I've heard of many compatibility issues for Radeon 5000 series GPUs on a 1.0 motherboard.

I had a E8300, 3gbs ddr2, g31 chipset (pci gen 1 like yours)on a dell vostro mini tower 200 with a HD 5450 (pci gen 2). The worse thing it did was black screen for half a second every time it booted up but then appeared and worked normally.

I used to own a G31 chipset too. The Intel Desktop DG31PR. I used to have an 8400GS, which should work fine on a 1.0 motherboard, but it showed similar problems. The screen would appear blank till it shows 'Welcome'.

I am going to buy 7750 but i wanted to just confirm somethings

1.can this GPU work with a 350 watt psu? its instructions say that yellow is 32A

2.will my DG31PR which has PCIe x16 Gen 2.x slot can pick up this GPU

3.i am not into BF3 or CRYSIS 2. i want to run MW3 at high and GTA 4 and newer games from mediuim to high settings will it have problems??? i dont care about graphics,what i want is performance.

if the psu's quality is good enough. if it isn't ... you don't want to waste a brand new gfx card a poor low end psu.
the gfx card draws power from pcie slot. most reviews i read showed that it uses around 43-44w on load. so it needs 3.6A~.

yes.

at you res. games tend to be cpu bound, so that will factor in as well (especially gta 4). i don't think it will have any issue running at medium settings.

i just looked and the hd 5770 is better than the hd 7750 and 5770 is cheaper and requires less watt. this websites indicate the same

Bottleneck?
Thats quite a high ranked GPU for such a CPU

don't forget to add ram. 32amps should be okay.

The HD 5770/6770 are almost equal when it comes to performance, and in some cases, the 5770 beats the 7750 by a small margin. And the HD 7750 takes less power compared to the HD 5770.

hwcompare only compares specifications, not performance. and where does it say 5770 (108w tdp) requires less watt than 7750 (55w tdp)? the 7750 may not outperform a 5770/6770 at every resolution but it offers very competitve performance at significantly less power consumption (110w vs 43-44w). besides, at your resolution (1024x768) it won't matter a lot. if 5770 is cheaper than 7750 at your location, then go for that one. but make sure you have a good psu as well because your pc will need it, no matter which gfx card you choose.

afaik dual core cpus don't bottleneck entry level gfx cards. c2d isn't bad as gaming cpu.... unless you're using multi gpu like crossfire or higher end gpus like 7850. it is also game dependent. in gpu bound games (which most games are), it won't matter.

so if i buy the 7750 1 gb ddr5 will it run ok on my PSU and wont overheat and die??

same question i asked De5_roy

so if i buy the 7750 1 gb ddr5 will it run ok on my PSU and wont overheat and die??

so if i buy the 7750 1 gb ddr5 will it run ok on my PSU and wont overheat and die??

and i just learned that windows xp is not supported by HD 7750 until the amd catalyst 12.4 release does anyone know when it will be out??

i went back and checked the posts. you never mentioned what/which psu you have. so there is no way for anyone else to tell. you listed it as 'local' so i assumed it's a low end one. the amps listed under +12v rail is important as most components draw power from that rail.
as for xp 32 bit support, check this link
http://www.anandtech.com/show/5715/amd-releases-catalys...
it says amd will add xp support next month.
if you're using xp 32 bit, there's no need to add extra 2gb ram as 32 bit won't be able to use it. you should upgrade to windows 7 64 bit, it can address 4gb ram which will help with gaming and improve overall system operation. 2 gb is marginal, but okay. games that demand more system ram might not run or run very slowly.

On a local PSU, I wouldn't suggest it. Best you get a good PSU from reputable brands like Antec, Corsair, Seasonic etc.
