Gigabyte Pc upgrade... or other

Ok, let me explain ... SLI means you run 2 or more nVidia cards, Crossfire means you run 2 or more AMD Cards (AMD took over ATI).
Now a board that supports SLI cannot run Crossfire, and Vise Versa ... so the XFX 790i will run nVidia cards in SLI, but not AMD Cards in Crossfire (It will however run a single AMD card),
The Asus Rampage Formula is based on the Intel X48 chipset, which will run AMD Cards in Crossfire, but not nVidia cards in SLI (But it will run a single nVidia card) ... hope this makes sense

it does in a very vica versa way of thinking

Intel Core 2 E8500
Biostar T-Power I45 DDR2 Motherboard
4GB Mushkin PC8500 RAM (2x2GB)
NVIDIA Geforce 9800GX2 (any version, the cheapest will do)

All the above should cost you less than R12K. Reason you may want to go with NVIDIA woudl be because of the PhysX support. I have been playing UT3 with PhysX and its awesome

You could spend the whole 20K for more VGA power though

Intel Core 2 E8500
Gigabyte EX38-DS4 (DDR2 X38 chipset)
2x Radeon HD4870
4GB Mushkin RAM (same as above)
This rig would still cost you less than R16K but would be mighty fast, in fact the fastest graphics solution money can buy (save for 4-way GFX and 3-SLI)
