The choices were:
MSi 660 ti - £237
Msi 7950 - £226
Msi 7950oc - £250
As far as i know the 7950s out perform the 660ti's but they seem to be selling at a similar price atm with offers. Games im currently playing are WoW and Dota, but i was told Nvadia's cards are better for those games but i've not had any problems with my ATi card so im not sure. Im leaning towards the 7950 because i like the games bundle that comes with them. Any alternative suggestion is welcome as well
