Choose me TWO bang-for-buck cards 
Requirements:
1st Card - For me - Play MMOs and FPS Games at 1920x1080. I'm wanting a mid-highrange type card that will play Crysis (the original) very well and is DX11 compliant. Quietness would be a major advantage.
Current Card: 4850 512MB (owch)
System to go in: i7 950, 6GB, P6X58D-E, SSD, Corsair AX850 PSU
2nd Card - For the Missus - Plays only MMOs, and at 1280x1024 currently (will be upgrading to 1920x1080 in the near future). Not much of a gamer 'enthusiast', but DX11 compliance required. Quietness would be a major advantage.
Current Card: 8800GS 384MB
System to go in: AMD X3 450, 4GB, GB 880G uATX, SSD, Corsair CX600 PSU
Budget: Upto £350 maxish for both cards. Prefer a bit less and hence the 'Bang-for-buck' approach.
