I recently bought a
X1950 Pro 512 AGP for my AGP system (along with a cpu upgrade to AMD 64x2 4800) and I think it's fantastic. I can run Oblivion at hightest settings in1680x1050 resolution on my 22" monitor! Until you see Oblivion like this, you aint' seen nothing. I figure my dated Asus A8V motherboard has another couple of years in her with this upgrade.
Just make sure you have a good cpu and at least 1 gb of ram (2gb is better) or you won't get the full benefit.

P.s., - OH - ONE IMPORTANT DETAIL!!! Make sure you use the Omega Drivers, not the catalyst drivers that come with ATI. You can download them here:
Omega Drivers. The Omega Drivers are rock-solid, stable, and have built-in overclocking. Trust me on this one, you will be very happy with Omega and ATI.
