ADDITIONAL COMMENTS: I'm hoping this is a decent setup for my first attempt at a new homebuilt system. I have a tight budget around $800 but I want a future proof system that will fulfill all my needs and then some. And of course blow away any games I throw at it. This build seems to be the best bang for my buck from allllll the research I've done. The only things I'm not sure of now are what case I need to put all this great hardware in and what monitor would be good in between the $100-$200 range for this video card. I don't need anything crazy like a $150 case or a huge screen, just a modest 20-22" monitor with at least 1680X1050 rez and preferrably hdmi as I have the setup for it. Lastly, just let me know if you think this will all be compatible and easy to setup and work properly! ANY suggestions, new hardware are greatly appreciated!!! Here goes:

(Curious about this new Ripjaws series, affordable ddr3 1600 ram for $80, I do like the other ram the have though that is $83.99 with very good reviews, suggestions?)

POWER SUPPLY / OPTICAL DRIVE COMBO:
OCZ StealthXStream OCZ700SXS 700W ATX12V / EPS12V SLI Ready CrossFire Ready Active PFC Power Supply

(I know I know, Corsair power supply all the way but this one has great reviews on newegg and is fairly new, also for $10 less than the corsair 650w I get this one and the optical drive I was wanting so some substantial savings there, suggestions?? not to mention the $20 MIR too..hehe)

This seems like a great budget setup, am I wrong? Again, I need to know where to go in terms of case and monitor matchups to this build. I think I am going to try and find some way around purchasing Vista 64-bit off newegg for the steep $110 mark and try to find it cheaper local. I will also be trying and buying a keyboard, mouse, and speakers I find in person as that can be tricky to decide on online. Thanks for your time, sorry for the extremely long post, just wanna make sure I cover all bases!

everything seems good but you might want to consider a i5 build which should be right in your budget. also i'd recommend this monitor http://www.newegg.com/Product/Prod [...] 6824236067 just got it a week ago and love it, also has a hdmi.
