Looking for upgrade advice

[Mack08]

Hi all, I've been away from the PC upgrading business for nearly two years ( bloody xbox 360) but I've got a yearning to go back to my flight / war sims. My current rig can hardly cut the mustard anymore so I'm looking for a little advice. I'd like to get a intel system as I've only ever had AMD and I'm not sure as to which is the better out of Nvidia and ATI. I'm looking at a budget of between £500 to £800 max. Bellow is my current spec, thanks for any input.

AMD 64 3700+ OCD to 2.7 GHz 333 MHz bus
Asrock dual sata 2 mobo
1024mb PC3200 DDR-DIMM 1024MB CL2.5 6ns
Powercolour 6800GS 16 pipelines
Western digital WD1200JB 120mb HD c/w 8mb cache
Enermax EG651P-VE 550W ATX PSU
WinXP Home edition SP2
Samsung Syncmaster 750s 17inch CRT monitor

your existing psu may be fine for the system, the hx520 is also powerful enough if you need the extra money

you also may want a new monitor
