Hello

Well, there is a question im interested in:
Can the system be too powerful for GPU?

For example mine:
Intel core i5 760 3.2Ghz
4Gb DDR3 1333Mhz RAM
Gigabyte 8400GS 64bit 512mb<------- Crappy ***, but it was doing its job for 2 years

More about : system powerful gpu

Your CPU IS faster than your GPU in this system.........

That's not a bad thing, some people don't need high end graphics cards. If your just websurfing, or doing office work this system would be fine.

If you want to do some gaming, photoshopping, or such you should think about upgrading your GPU....

Pick the game(s) you want to play. Goto Guru3D and look them up to match them to a GPU that will give you the FPS you want at the resolution you are running.....

Start with something like a 5770 or GTX 460 .............. work you way up from their.

NOTE: What power supply brand and wattage do you have? 400-500 watts will work for these cards. You'll want a 650watt supply for a higher end card.

nope, if your CPU is stronger than your GPU there won't be any "bottleneck", only if your GPU is much stronger than CPU you might have issues

I know my CPU is much better than my GPU.
I am getting a new GPU in next 2 months but i dont know which should i take. (for 1280*1024)
I want to max games like CoD, Battlefield 3......
Also, i need a new PSU.

Oww, and now i have a Codegen 400W PSU :D

Well, going to Guru3D and looking up COD:

http://www.guru3d.com/article/geforce-gtx-590-review/11

This game isn't a tough load for a GPU... so just about anything will do...

Going to Battle Field 2, ah, need a bit more GPU power to this game....

http://www.guru3d.com/article/geforce-gtx-460-se-review...

Looking at a basic 460 review we see that it will get the job done....

SOOO, I'd stick with my original Recommendation; get a 5770 or GTX 460 ..............

Maybe a GTX560Ti or GTX570?
Cuz i want to be sure that my system will be futureproof(for 1-2 years on max)

AH, yeah that supply won't work ... with Only 14A on the 12 volt rail

Here's a 5770 review they state you should 500watt supply for a highend system with 40A on the 12volt rails (total)

I prefer Antec, Corsair, and Seasonic power supplies....

Here's a low cost example:

well 450W PSU barely works with 460, 460 needs a 500W PSU to work good @ stock and 550-650W PSU to work after OC, while 6850 OC *and stock* can do the job better than 460 with a 500W PSU, btw 5770 isn't a much of a good card and i personally would get 460 over it, cause it *and most of nVidia cards* runs better on lower resolutions

strain on the cpu? how do you figure? its not going to hurt the CPU. I disagree that above 5770 is overkill, once you add 4x or 8xAA you need more power than a 5770 in many games.

anyway the OP has a cheap 400w codegen psu, he wont be able to run anything better than a 5770, and that would be pushing it. The PSU will probably blow up, if not now, less than a year down the track.

Vsync sometimes cut the fps half the refresh rate which leaves you not much room for any emulation like AA.

this only happens when your fps drops way below the refresh rate (say40) and then the vsync 'cuts it in half' ending up at 30. At the ops resolution 5770 wont have any problems keeping it up at 60 in most games with decent quality (if not maxxed out), I should know since I have 5770 at 1280*1024 running with vsync on.

and having a powerfull gpu at low res won't hurt the cpu, that's why it's there: to do its job. Even if you max it out it won't mind and you get massive fps, some geeks seem to love it lol
