Unfortunately, we can all look at one price and say "hey look, it is cheaper". If you take a look at our price compare engine you will see that on average the HD4870 is cheaper than the GTX 260 before MIRs.

In addition, before everyone gets bent out of shape I have to remind you that this review was about the BFG GTX 260 and many pricing comments were made in relation to that particular card.
Too bad that engine doesn't actually work that well, click on the lowest HD 4870 price " Visiontek Radeon HD 4870 "
Supposed to be 249.99 @ ncix... nope 294.99 @ncix
But I do agree that the the price comments were made on the particular GTX 260 card... but I do think that the GTX 260, and HD 4870 should be compared as a whole, and the price comparisons should be based on the suggested Retail prices from NVIDIA and ATI... because as you said we can all claim one or the other is cheaper.
