Hi,
Be a little bit backward when it comes to reading hardware specs, I need alittle bit of adivice from those of you more in the know.
Currently I am running a system I build some time ago and am considering upgrading to squeeze a bit more graphical performance out of it.
Asus M2N32SLi Deluxe, Athlon 64x2 5600+, Corsair 2GB DDR2 675MHz/PC2-5400 XMS2 & 2 X 256mb Asus Geforce 7600GT's running in SLi.
It was made for MTW2 and ran that pretty well, then experienced a few issues with ETW but this was more the software than the hardware, and now playing NTW fares pretty well (once I had updated the drivers) but slows when I pan down to ground level.

So, thats the background, now what I am considering is replacing the graphics cards and adding a little more say another 2gb of memory.

I can get 2 X 1Gb 9800GT's at about £130 for the pair, the question is for a similar budget is there better options available that will give me a noticable performance increase?

Thanks for any help in advance.
