Well, I thought I'd update you on what I've done
I finally decided to buy a relatively normal 7800GS to tide me over until I basically buy a complete system when I decide to upgrade to Windows Vista and DX10 graphics. Although I didn't realise at the time, I just got the Leadtek card
Orangat recommended as it seems competitively priced, potentially has 20 pipes (its not actually confirmed whether it is 16 or 20, there have been lots of conflicting reports on it, but the cores are definitely G71's not the normal G70's), and has a decent amount of overclocking potential, but the clincher was it came with 2 decent games that I don't have, but have considered buying at some point (Splinter Cell: Chaos Theory, and Prince of Persia: Warrior Within)
