Slightly over budget but given they can flash to 6970 they are awesome bang for buck really.

i would suggest a GTX480
its £206, and comes with far cry 2.
however, its quite a power hungry card, so im not sure if his power supply would be up to the job
whats the rest of his build, and how old is the power supply

Power supply was got last month and the rest of his system is;
Q6600 @ stock
4GB DDR2
Was looking at the HD 5850 before I posted this, seems a good card for the price. Much better than his old 8800gts anyway.
