Our review of the NVIDIA GeForce GTX 295 showed that it was far superior to the the standard GeForce GTX 280 while consuming only 23% more power (289W vs. 236W). On average, it was about 50% faster than the GeForce GTX 280 and 80% faster than the GeForce GTX 260. That's a significant boost in performance, something NVIDIA really needs to spoil ATI's winning streak.
Of course, the GeForce GTX 295 has a really hefty price tag, which makes everyone wonder if it's worth buying when there's a virtual fire sale of GeForce GTX 280 and GTX 260 cards. If the GeForce GTX 295 is really overclockable, then it might be even more worth buying than the GeForce GTX 280 and GTX 260 cards which are still using the older 65nm GT200 GPUs. Let's find out!
