So i'm thinking about backing up to an external and 2nd internal hard drive. Formatting and installing the win7 early release. Win xp pro sp3 black,gentoo and solaris tri-boot right now. Reinstalling Solaris and gentoo on a tri-boot with win7. My question is this? Vista really set me back and I downgraded and lost some data in the process. Is win7 a relentless cpu and ram background component waster like vista? With a donkey load of driver and third party conflict problems all that? I'm scared dude winme and vista really made me question microsoft's power level because it surely is not over 9000 now. I need my third party stuff,dev kit apps,drivers,hardware and software in a functional state. 4 GB DDR2,3.0 ghz quadcore over clocked 8 mb on board,nvidia 9500 with 1 gb on board,250 gb,750 gb sata internals 7200 rpm,XFX MG-610i-7059 GeForce 7050 Socket 775 Motherboard,Apex SK-386 ATX Black Mid-T Case w/ 300w PSU,Dual PCI Slot Fan on medium speed. Anyone have xp points in win7's ram and cpu consumption? Performence issues?
