Video Card Question

[vgame128]

Hello, i'm new here, and have a question:

My configs are:

Dual Core E5200 @3.2 GHz
2GB Ram DDR2
ATI HD 4670 512mb

My question is:
If i change the video card to a Geforce GTS 250 Core Edition 512 Mb, i will have a better performance?

I'm getting most games a decent speed, but sometimes when i change the resolution to 1680x1050 (my native resolution) , the FPS drops.

Please answer me, THANKS!
(Sorry my bad english, i'm from Brazil)

I don't think so. Those cards are pretty close in their specs. Overclocking your processor or upgrading to a better one will help more.

yeah, you'll probably get no differences if you switch.
