i believe on newegg 7900 costs less than the 7800. if u cant afford anything better.....go with the 6800 or 7600GT, and save up for the G80s later on. an drop the DFI Lanparty SLI-DR and go with a MSI K8n Neo4-f
XFX is a great brand, so drop from the. K here is what i have got so far
Drop MOBo to MSI K8n neo4-F ( you save $95 or something)
then drop from the Kingwin to ANtec TruePowerII 550Watt, one of the best PSUs btw, and you save about $5 +$95=$100, so just add $10 and you can upgrade the 7600GT to the 7900GT.
am i good or wat.
