Thanks for the advice guys...
I have looked at the card...and the prices...hmmm...
One thing I have noticed is that most of the newer cards require a PCI-e 6-pin additional power supply...and guess what - my supply dun't support that

- hence the reason for my list...
So - I'm looking at a new PSU, as well as a new card...I've looked at both the Radeon 6850 and the NVidea GTX4xx....nice cards but a bit pricey...
I have been told to go for a Radeon HD5750 - any good? Its priced reasonably at 90 sterling pounds, and has 1Gb DDR5 memory and is DX11 compliant...
BUT - the Nvidea cards have the PHysX module - so was wondering if this makes any difference at all? I knwo that TGC recommend Nvidea - but putting a Radeon in the machine - woudl that slow down anything???
