I've just upgraded my monitor to a BenQ XL2411T but my 7950 is struggling at 120hz with games like BF4 etc. I do like to run games at higher detail levels and was looking into xfire but these 7950s have shot up in price lately and frankly I don't really want to buy a more powerful PSU either (currently have a Corsair TX650v1). So, I'm looking for a new card... I have a budget of between £400-£600 but ideally want to stay at the lower end of that. I really like the look of the 290s, especially with Mantle around the corner but a work colleague bought a VTX3D 290 that has severe black screen/freezing issues despite it being RMA'd twice and subsequently declared working by the seller. So, any suggestions are welcome. Many thanks.
