HD 5750 vs HD 4870 vs GTS250

he guys. I am thinking of buying a gpu.these three cards have same price where i live so its hard for me to decide which is better.

my cpu configuration is

q6600 core2quad 2.4

asus p5kpl-cm

kingston 2048 mb/800

500watt coolermaster power suplly

can you elaborate please.actually quite confused!

The HD 4870 is easily the most powerful card among those three. The GTS 250 is the weakest.

The HD 5750 will support DX 11 however its not fully implemented yet so I would go for the 4870. It might not support DX11 but games will run better on it.

Both ATI cards mentioned are much more powerful than the GTS250. Good card, but I wouldn't even consider it in this discussion.

so 4870 is the way it is meant to beplayed ;)
