I have been looking at building a computer system and I am wondering if buying a GTX 670 now would be a waste of time considering the GTX 7xx series is just around the corner. I was thinking that I would just get a GTX 550ti for now and when the GTX 7xx series comes out (or AMD 8xxx series, depending on which one is better) just get one of those and drop it in with the 550ti as a Physx processor or perhaps just an extra card to play around with.
The specs that I'm looking at are as follows:
XClio Godspeed Advanced ($55)
Intel Core i5 3570 ($218)
MSI Z68A-G43G3 ($109)
Asrock Z77 EXTREME4-M ($125)
WD 500GB CAviar Blue ($68)
Kingston Hyper X 1600mhz 2x4GB ($55)
Thermaltake TR-600P TR2 RX ($85)
Gigabyte GTX 550 TI 1GB ($117)
Will this system be OK to just drop in a 780 and go?
Which motherboard will do the job better?
Is the whole idea a good one in the first place or should I just get a 670 now and SLI them later when the 7xx series comes out and the price goes down?
Thermaltake TR2 RX 750 W is, according to our methodology, a flawed product that must be avoided at all costs. It can’t deliver its labeled wattage at high temperatures, but this is not the worst of it: ripple and noise level are way above the maximum allowed when you pull 80% or more from the unit’s labeled capacity (i.e., 600 W and above), overloading your components (especially electrolytic capacitors from the motherboard and video cards), which can cause your PC to present an erratic behavior (crashes and random resets) and, under extreme conditions, damage components.
futureproof you say? go with the z77 board, the msi z68 board doesn't have a usb 3.0 header and future cases will surely have usb 3.0 headers as usb 2.0 gets replaced by usb 3.0. I think you need to get another PSU. Thermaltake are not really good in power supplies. Go with trusted and proven brands like corsair, seasonic or antec.
