I'm doing some shopping for a Graphics Card. The ATI Radeon's or pretty strait forward, I get those. NVIDAI however has multiple chips it seems... Mainly the GeForce; GTX, GTS, FX, # Series... etc. So what series of NVIDAI are current/up to date? I'm looking for something comparable to the Radeon 5770 or higher, within a budget range ($100-$200). I really don't know what to choose from the two different manufacturers. Is one better than the other? I'm somewhat familiar with the Radeon's... I guess I'd just like a comparison.
