Upgrading major parts

I am thinking about upgrading some major parts on my system and just want to see if I can use my current Case and PS.

I am really close to just ordering an i7, mobo, 6g of ram and a vid card. Looks like i can get these 4 parts for ~$900.

Ram....6GB of something
Vid Card.....?

I am not sure exactly what type of ram or vid card I should get. I dont mind having all vid setting in wow on min with main window distance settings up a little. So for the price, is GTX 750s a good buy?....compared to the 850s? I am guessing if there is anything i could upgrade in a year or two it would be the vid card, so atm im leaning on going for a mid range card that will stil put out to run 5 wows.

Will these parts fit in my case? And will 650W be enough to push these parts?

Thanks.

I did not see any 4750's listed on Newegg. A 4850 1GB for $125 is a sweet deal, should run 5 WoW's just fine. I would go there or a 260/270 nVidia.

The 4850 I looked at called for a 450W minimum PSU, so you should be ok with a good 650.

Sorry, I was was talking about the Nvidia GTX 750-850. But, Nvidia or ATI....i can go with either. Just wondering if a $200-150 vid card with a i7 system will be too much of a bottleneck for running 5 wows?

And, is there any advantage of getting LL ram or any better timing ram than the norm?

ATM, I am running a 5 year old system: AMD 3200+, a good AGP card, and 2.5GB of DDR ram.......so any "newer" system will be far better than what im running. I am thinking that if I am spending money on buying a system, might as well and make the jump to i7 over a Q6600 build. Or am i just wasting money going with the "new" technology?

A $200 video card will do fine for WoW, it is not a heavy graphic game. If you also want to run the latest FPS then you might want a slightly better card.

Stack RAM will work fine, you have to Major O/C the CPU to catch up with the FSB and RAM numbers.

If I were building a system right now with no parts to upgrade with (drives always upgrade) I would go with i7 system. It costs more but has a lot more upgrade/future proofing on it.

Cool deal, ty for the help.
