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.
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.
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
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
