You can certainly get that system, it would serve you well, but, personally, unless you are trying to get every last frame per second out of a game, an AMD system might be more cost effective. One of their Phenom II X6 CPU's would probably equal the performance, more so if the programs you use demand actual physical cores instead of hyperthreading, or if they can use all six cores. You do not need a 1KW power supply in a dual GPU configuration unless you are using the GPU's that have two GPU's on one printed circuit board, like the Radeon 5970. For two GTX 460's in SLI, a 750W power supply is all you really need. What seems to be the issue with ATI/AMD graphics cards with your program? According to the specifications I've seen, any of AMD's recent GPU's will run OpenGL 4.1. As for what is more powerful than a GTX 460, it is outclassed by any of the faster Nvidia cards, the Radeon 5850 and up, along with the Radeon 6800 and 6900 series. The Radeon 6850 is a little more powerful for about the same price, the 6870 more so, and both the 6950 and 6970 cards are far more powerful. You should get whatever works best for your given situation. Although there are more powerful cards, it won't do you any good if you cannot use them for your purposes. BTW, with multi-GPU setups, getting a single powerful GPU is often best rather than two mid-range GPU's. This comes from gaming where not all games are able to fully use Crossfire/SLI equally. If a game has performance issues or simply doesn't scale well, thus requiring it to use only a single card, the performance gap isn't quite as painful since one high-end card can play most games well at higher settings, unlike the performance of a single mid-range graphics card where it would be a much slower experience.
