I love how people use the GPGPU argument.
GPGPU performance is useless to all but about 5% of the desktop market. Why make a GPU awesome at GPGPU for a market in which it will rarely be used. You might as well nerf the GPGPU performance, increase raster performance drastically and give the people what they want, gaming performance.
Its exactly what Nvidia did and you know what, good on 'em. Finally they are using their brains and realise that they are almost a monopoly in the workstation side of things (Nvidia pwn AMD in workstation cards), Tesla is giant cash cow and now, by concentrating on raster performance with their GeForce cards they are essentially catering products to all 3 markets (desktop, workstation, supercomputer). In essence, this will force AMD to go down a similar pathway. It will force AMD's hand and make them develop new FirePro (Or w/e their called) workstation GPU's and then reduce the GPGPU performance of the Radeon cards to increase raster performance enough to compete with the GeForce cards.
Either way you slice it, Nvidia end up winning. Workstation cards powerful enough to compete with some of the beasts Nvidia have on offer will take AMD multiple generations to develop, by which point, they would have lost considerable market share in the desktop range due to Nvidia continuing down the route of 3 individual products for 3 individual markets.
So this is really just Nvidia strengthening their position. They will start to narrow the margin in regards to desktop GPU market share and their QuadroFX and Tesla cards wont be going downhill any time soon. So very smart move by Nvidia, whether some of the fanboi's on here would like to agree with it or not. There is no denying that ultimately, Nvidia are on a pathway to success. Especially when you factor in that in reality, it will be a battle between Nvidia, Intel and ARM in the low-power ultra-portable market over the next 3-5 years.
In reality all Nvidia did was give the people buying GeForce cards (gamers) more performance at the loss of computer power. In the end, computer power means nothing to gaming and as I mentioned before, I would be very surprised if any more than 5% of the desktop market even used software where they would notice a difference in GPGPU performance (actually notice a difference, not have a benchmark tell you photoshop loaded 5ms faster), so Nvidia are doing a good thing by consumers
