Yeah, the 750psu is more than what I needed, but I wanted to be sure I wouldn't have to update the PSU along with getting a second video card if/when I went the SLI route. I was fine having too much with the PSU as it allowed room down the road.
Thanks so much re: the mobo. I'd overlooked that. Also, I'm pretty sure I'm kidding myself with OCing and should really save money with the cpu. That said, again, I wanted something that had the room. I'd upgrade the fans/cooling at that time, then.
But recently there are lots of speculations about the Ivy Bridge release date since there are some alleged compatibility issues regarding UEFI BIOS motherboards and PCI-e 3.0 support. If the UEFI BIOS is an issue then it will be up to mobo manufacturers to take care of that. This concernes me since I have P67 Sabertooth board.
Haven't seen any Intel official statements so far, but there are 2 unoffical dates, November this year and Q1 2012, not sure which one is correct. Or maybe Intel is just waiting to see what AMD Bulldozer will deliver.
i was thinking on moving to Alienware Laptop is it ok idea ?
If you have deep pockets, sure. I have a M1730 (before Dell bought Alienware) and it's a great notebook (dual GTX 8800M). They are usually pretty big/heavy though, so if your goal is to go to LAN parties but use it while it's plugged in, then it's a good idea. Otherwise, they are so power hungry than they are not very good for playing while using the battery only, the performance will suffer and you will run out of power very quickly. If you don't plan on using your computer outside your home, then obviously you would be better off with a regular desktop PC as it will be much cheaper for the same performance.
