I think you got that confused I wasnt aware that ati made x1800xt in AGP??
NE wayz my personal choice would be a Evga 7800 gs sc
Before I decided 2 upgrade 2 PCIe, I did days of research and the 7800gs sc won my heart, I mean yea, I am an Ati fan, and the x850pro which sells about $200 is a great card, but the 7800gs sc (super clocked)
has sm3.0 much better performance than the x850pro, bu ffffaaaarrrrrr.
I you are in no hurry to upgrade to PCIe, the 7800gs sc is the smartest way to go, it will last U at leat a year and a half even more, if your system is pretty riged up :wink:
Great card for value and not to mention performance wise.
So YES the EvGA 7800 GS SC is the card to go!!
P.S keep us posted
