BitTech: As we can see from the real world gaming performance, it will ultimately depend on the title. For example, Half-Life 2 showed a relatively small performance improvement over the previous generation GeForce 6800 Ultra, but it was still faster than GeForce 6800 Ultra SLI in both single and dual card configurations. The majority of other titles showed that GeForce 7800 GTX was faster, with the exception of Doom 3 and Splinter Cell: Chaos Theory, where the additional 256MB frame buffer on the second video card helped to improve performance ever so slightly. We believe that a single 512MB GeForce 7800 GTX would be enough to give GeForce 6800 Ultra SLI a run for its money in these titles, as the issue seems to be more frame buffer related rather than pure pixel pushing power.

TechReport: As for whether or not the GeForce 7800 GTX is a smart buy, that is another question entirely. The 7800 GTX is so powerful, not many current games are able to take full advantage of it. We threw some of the most graphically intense games around at it, at high resolutions with lots of edge and texture antialiasing, and at times, we were barely able to make it slow down. Yes, the 7800 GTX is grand progress on the semiconductor front, but do you want to pay $599 in order to fund GPU research and development? Or $1200 for the big prize of an SLI rig? You're certainly getting a lot of rendering power for all of that money, but not many apps will use it. Perhaps the bragging rights are worth it for some folks, but for playing today's games, I'd probably settle for a GeForce 6600 GT or a Radeon X800 XL. I'm cheap that way, I suppose.

Guru3D: Ehm, let's see what more did I find. Ah, very interesting is that power consumption actually was lower then the Series 6 high end products. Your average 350 Watt PSU is capable enough with the card and an average system. Our Athlon 4000+/512MB/100GB-HD/DVD-Rom/7800GTX based system peaked at just over 260 Watt, charming. What you do need to be aware of is that this little gem requires a really fast CPU though. A high-end graphics card needs a symbiosis with a high-end PC. 3.4 GHz Pentium 4 or a rather sizable AMD64 Athlon 3400+ is something you need at the least for real. Even with our Athlon 4000+ testing rig we ran into CPU limitation here and there
