New Graphics Card

[duhoh]

I dunno what to tell you. I use dual channel 2gb (800mhz) and it runs foobar + palemoon + steam + any game i usually play just fine. i have another 2gb stick that i mixmatch and it feels like performance drops and also the clockspeed needs to be adjusted to 667 due to the technically third stick being a lower set clockspeed.

 

then that's your fault for mix-matching.

Go for the GTX 460 and go sli later if you want. The reality is that unless you are running at super high res with 8+ AA enabled, a GTX 460 will run anything you throw at it. As far as I can tell, until consoles move on to the next generation, no developers are going to me making a game that requires more than a 460 to max. Though if you are planning on that 3d on 3 screens at once thing, higher end cards may be what you need.

BTW, Potshot is nearly always right. I would get 4GB of ram if I were you. Just dont do what I did and get 8gb. Turns out I dont actually need 8... who knew?

I'm going to be frank here, your general computer is lacking for gaming. If you want to play Crysis 2 when it comes out you'll at least need a Quad Core (I would recommend a phenom)

Then get a compatible motherboard with DDR3 Ram compatibility, I would also try and get a motherboard with USB 3.0 support, and maybe SATA 6GB/s.

 

Ram - around 4-6GB

GPU - I would personally recommend the HD6950 - http://www.scan.co.uk/products/2gb-msi-hd-6950-pci-e-21-(x16)-5000mhz-gddr5-gpu-800mhz-1408-cores-dvi-mhdmi-mdp

 

Your current specs wont run Crysis 2 very well, yes it's an accusation but one I'm sticking too. Be warned, it's going to cost around £600+ for a GOOD gaming computer.

you know if you get that ram and gpu and it still wont run well you could always buy a big cooling fan and OC the the hell out of your cpu.

Get a 6950, you can flashed them to 6970 default speeds and then overclock it.
