So, I'm looking to buy a new PC, something to future proof and run the games I generally play and I would also like to know how much better it will be than my current one (I'll put the details on before the PC's I'm currently looking at).

I play a lot of FPSs and MMORPGs (used to be GW 2 until it was all samey) and I was wondering out of these three systems, which would you recommend value-wise and performance-wise.

Thanks for any input!

My Current PC

600W PSU

1TB Harddrive

AMD Phenom II X4 970 Processor @ 3.5Ghz

4GB RAM

Nvidia Geforce GTX 570

Asus Xonar D1 Soundcard
