But you're going to need a really big screen in order to appreciate its twin-GPU prowess. Owners of lower resolution screens can spend a lot less money and enjoy just as fast frame rates. What the GTX 295 does have in its favour is that it's a single card solution that works straight out of the box. Oh, and the fact that it's the fastest card around. It's not a must buy, but if you missed the last generation of upgrades, this is the card that should fulfil your dreams.
