Re: which video card
65nm vs 80nm, 120 shader processors vs 16 (plus a higher core clock), higher memory clock with same bit-interface. All favoring the 2600PRO.
In simpler terms, it just is.
ASUS A8N32 SLI-Deluxe, AMD Athlon X2 3800+ @ 2.8GHz, eVGA 8800GTS 320MB, 2GB Corsair XMS DDR400, 160GB WD HDD + 320GB Seagate Barracuda 7200.10, AC Freezer 64 Pro, 700W OCZ GameXStream, NZXT Zero :D
I think I've decided to leave... maybe I'll come back sometime.
