I should have provided more info...I have an existing 295 that I've pulled b/c I upgraded to a pair of 570s. Therefore, no worries about acquiring the 295
The 450s are on sale at newegg for about $110 each b/f rebate, so I'm looking at about $200 out-of-pocket. I figure the sale of the 295 would cover that, and probably leave me a buck or two left over.
So basically, the question boils down to keeping my current "pulled" 295 or getting a pair of 450s in sli in order to utilize DX11.
Thanks in advance.
