The HD5570 is similar in performance to the GT 240. Both of them come in DDR3 or DDR5 varieties with the DDR5 cards being noticeably better. If you can afford an HD5670 or 9800GT that would be ideal for a low end card.
Yeah, that board has UCC so it will be able to unlock the fourth core. It's not guaranteed to work but there's a very good chance it will from what I've read.
On cards of this caliber more than 512mb of memory isn't particularly useful so don't spend more on it.
Also there are two versions of the 9800GT. The normal card has a 6-pin power connector while the other is lower power and lacks the connector. For the regular version make sure your power supply can handle the card.
Looking on ebuyer the HD5670 seems to be slightly cheaper than the 9800GT. I would recommend it over the 9800GT if that is the case as it will give you similar performance and add DX11 compatibility.

Thanks for the help, the 9800GT was only a few £'s more expensive, and I have ditched my HDMI cable after realising the monitor I'm getiing only has DVI, so it's wound up being £415 overall, which is fairly good price for the amount of power I'm getting, I will have to upgrade to 4gb of RAM when I can though, just for a smoother ride.

I didn't see that, sorry, I'll get a 5670 instead then, £410 overall, not bad, thanks very much for the help.
