No, it won't cope. Whats your budget? They got a great deal on Ebuyer at the moment, a Gainward 6800LE for 130, inc vat. I got one myself, and was able to softmod it to get the extra 8 pixel pipeliens and 2 vertex shaders working. Very good card.
Aim for 9600Pro if your on a tight budget, or go for 6600GT or 6800LE/NU if your feeling flush. Avoid Nvidia FX series of cards, tey have lousy pixel shader 2 performance, which really hinders its future proofness.
