I have the opportunity to buy an x2 3800 (s939), asus a8n sli deluxe mobo, 2 gigs of ram (g-skill) and an EVGA 7900gt (or possibly a second one also) from a mate for a very good price.
Will i see a substantial increase in performance over my current system:
Athlon 64 3700 s754
gigabyte nforce 3 mobo
1.5 gigs corsair value select
xfx 7800gs extreme edition agp
Is it worth the upgrade?
