£200 ish - What card???

[Lloyd_mcse]

Ok guys,
I have about £200 - so what GFX card to buy?

ATI 4870 1GB

ATI 4850 X2

Or an nVidia of same price

I haven't had the time to read up about the 260GTX. This is really a stop gap, so i can put the 8800GTS (in rig 2) in my bedroom PC - I knocked a capasitor off the 7950GX2 I have up there atm
Rig 2 is what my other lodger uses for gaming, so it has to be a good gaming card
Thanks in advance for your help
kind regards

Lloyd

Bedroom PC atm :
AMD X2 5200
Asus M2N32 SLI Deluxe
4GB Corsair 6400
eVGA 7950GX2 Superclocked
2x 320GB Samsung RAID 0
1x 500GB Maxtor
1x 500GB Samsung
1x 750GB Samsung
Antec P182 Special Edition
Seasonic 600watt

So the 8800GTS would be a nice little upgrade for it
