are the two 4870's 512mb and the single 4890 1gb ??
what about the monitor ?
Actually, on closer inspection I'm an idiot. It's not two 4870s, it's a 4870 x2, which I'm not totally sure what it is. Costs more than the 4890 though, so I assume it's better! It's got 2GB of memory, but I think that translates to 1GB because it has two cores or something.
Would you consider a Core i7 processor instead of a Core 2 Quad, or are you restricted by price when considering the processor amongst other things?
This is the machine I've decided to get, especially as it's on special offer this week and thus very reasonably priced:

With the 4870 x2 and a Antec 902 case.
So it's already Core i7.
