Does that GeForce Card have DDR RAM? If it doesn't, I'd get one that does - it gives a boost to performance.
Also, it occurs to me that the Athlon 850Mhz chip was released this month, which is faster than the Pentium III 800Mhz. Even if you don't want an Athlon machine, Intel are sure to respond quite soon and bring out an even better chip.
Personally, I'm holding off a little while myself from buying any new computer. Although I have a lowly Pentium 200Mhz with a Voodoo 1 card, most of the games I have will run at an acceptable frame rate - including Unreal Tournament and Wheel of Time. So I haven't got the highest texture settings, and not everything is switched on, but for now it will suffice until my dream machine becomes available.
Intel and AMD are supposedly going to release 1Ghz+ processors in the third quarter of this year - but judging by last year, I think they'll bring those release dates closer
Maybe I can convince my wife to buy me one for my birthday (in June), then I can spend my savings on all of those wonderful games that will be coming out.
Now there's a thought...
'I have a very bad feeling about this.'
