Heh I still have a 4600 somewhere. Overpriced but I loved that card. I had to.
If you go on AMD's forums you may find a frantic post about x2 technology. I did for a while until I also read the same type of posts put out by frantic people on Intel platforms also.
When I bougt my system the x2 duals were priced obsolete. However I got a dual supermicro board with some 246 chips that are so stable fast and smoking. Oh and did I mention the almost imfamous Upgradeable word? They are cheap also. Those boards take ecc reg memory tho.
I was lucky and found a supplier on ebay that was selling Top tested used memory from servers. It was the only real cost cutting chance I took.
Btw the new video is the 7800GTX and after all of the new software and hardware upgrades and bloatware
your machine is probably as fast. heheh j/k
Good luck.
