Notice:

I’ve tried a set of GTX480’s within SLI however the 3D recognise scores can be lower than two GTX295’s (Quad SLI) at a resolution with 2560×1600, which is the only resolution WHEN I use with regard to gaming.I are unable to use about three GTX480’s as you will discover not more than enough free PCI-E slots.

Also I obtained to cherry opt for my CPU, so that it is doubful that gonna a i7-990x will probably be any more quickly.

Tri-SLI GTX570 or maybe GTX580 (The 3GB version in the GTX580 would come in handy with your resolution)
4 -way SLI GTX580
Quad SLI GTX590 (Nvidia is actually revising it so that it won’t setback when overclocking)
Tri-Xfire 6970 or maybe 6990/6970
Quad-Xfire 6990

Each one would very easily blow your Quad SLI GTX 295

Your pc is quite best.You don’t to enhance the system.just more often run system defragment application and thoroughly clean the previous registry.
