Need a graphics upgrade


Sep 20, 2009
this is my system

ASUS A8N32-SLI Deluxe 939 NVIDIA nForce4 SLI X16 ATX AMD
BFG Tech BFGR7950GX21GBE GeForce 7950GX2 1GB 512-bit GDDR3 PCI Express x16 SLI Supported Dual GPU Video Card
AMD Opteron 185 Denmark 2.6GHz Socket 939 110W Dual-Core Processor

I dont know if i should start buying parts for a new computer or upgrading the graphics card...first what is the best graphics card i could get with this mobo. and second should i just start building a new machine. i know most will say start building a new machine but im pretty short on cash and i probably would only be able to put forth 100 dollars a month for a new computer
