Okay. So.
I'll be popping for a new computer sometime in May. This will be a Dell system, since I can't assemble a computer on my own, nor do I have the resources to coax someone into putting one together for me.
I've found a model of desktop that's relatively inexpensive and offers the vast majority of the options I want in a new system, save for one catch. The only video cards offered are Intel's Integrated Extreme Graphics (which is what I have now and won't be purchasing again, as it's not fully HTL-compatible), an Nvidia GeForce FX 5200 (128 MB), and an ATI Radeon 9800 Pro (128 MB).
I've heard good things about ATI--and they power my GameCube--and the general consensus on these boards seems to be "GeForce sux", so I'm leaning toward Radeon. My next question is this: If I shell out about five hundred extra dollars, I'll be able to purchase a more capable Dell model that supports A) A P4 3.4 Ghz processor as opposed to a 3.2, and B) an ATI Radeon 9800 XT (256 MB).
Assuming that Radeons are in fact better cards, I ask you: is it worth $500 for the extra graphics memory and the increase in processor speed?
