Sold my copy of BF4 yesterday for £23 that i got with my 290, so basically i paid £277 for my 290 and a copy of Hitman and Thief.. not bad
I got the same card (and redeemed for the same games) except i got a little more for BF4.
Cracking card for £270, less if you sell thief
Have you tried overclocking yet?
I found 1150/1500 to be the sweet spot for fps gains, anything higher on the memory resulted in negative gains. Can't quite get my core up to 1200 without artifacting though.
