My next choice of motherboard

Yes I have got the 6600GT. If i was to go to SLI it would require new motherboard, processor and two PCI-E cards which i just can't afford right now

Gigabyte GV-K8T800, AMD Athlon64 2800+,
1024MB PC3200 Samsung DDR, XFX Geforce 6600GT 128MB DDR3, Maxtor 80GB 7200 HDD, NEC 2500A 8x DVD Writer.
