Critique this build !

Heyyo!

I've accumulated quite a bit of extra cash over the year and plan on burning some dough on a new gaming rig (I'm still on an outdated P4/AGP rig). I've put together a basic outline of something I'd like to build. I'm open to any general advice or suggestions, as I'm a noob with hardware, so if I made any lackluster choices feel free to correct them!

United States ($) and ordering from Newegg by the way.

Goals: A rig that's semi-future proof (you know what I mean). I'm not a benchmark enthusiast or anything, so I don't want complete overkill. Graphics mean almost nothing to me. It would be nice to max specific settings, but not at the expense of blindly throwing money away for a few extra frame rates if you know what I mean. Basically, as long as I can stick with a solid rig for a few years down the road and it enables me to play games (even on low settings, as long as it's playable) without a significant frame drop, that'll be fine. The reason I picked this mobo/gpu combo is because in the future I could always crossfire in another 1-2 4890's, OR simply upgrade to a next-generation GPU down the road when more graphically demanding games come out, and I'm instantly good to go without needing to completely overhaul to a new rig/platform.

Budget: None, really. I have more than enough dough to blow off on a PC, but please try to keep things relatively affordable. Use your own judgment with this one. If you have a recommended product that might give me more bang/buck performance, be it a higher OR lower price, don't hesitate to let me know! However, I obviously don't want to blow off $1k on something like Intel's higher-end i7 for just a slightly faster cpu that's obviously not worth the price tag.

Questions/concerns:
1) Is that SSD worth it? I know SSD's don't have the best price/performance ratio these days, but since price isn't much of a concern, would it be worth it to invest in this SSD and install my OS/primary games on it? If they increase my PC boot-up/game load times like what I've seen, I'm all in for installing an SSD.

2) What are your thoughts on the PSU? Is it adequate for future upgrades? I'm thinking it already might be complete overkill, but I wanted to leave some room for future expansion.

I'll also be ordering Vista 64 bit with the free Windows 7 coupon (any recommended edition, anyone?). Anyway, I believe I've covered nearly everything. If I've forgotten anything at all just let me know and I'll get back to ya!

Thanks a lot!

APPROXIMATE PURCHASE DATE: 1-2 weeks I guess?

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming

PARTS NOT REQUIRED: Whatever I didn't list I already have or will be picking up locally.

PREFERRED WEBSITE(S) FOR PARTS: Newegg

PARTS PREFERENCES: Any.

OVERCLOCKING: Maybe CROSSFIRE: Maybe

MONITOR RESOLUTION: 1280x1024, might expand in future.

ADDITIONAL COMMENTS: Again, the reason for my choice in the 850w PSU is to leave room for these uncertainties in my build (overclocking, crossfire, higher resolution etc). However, I'm a noob with hardware so if there's something you'd do differently in this situation, feel free to let me know!

Not really to much to critique... Looks solid! As to the PSU there's nothing wrong with it but check this one out for a little cheaper http://www.newegg.com/Product/Prod [...] ModXStream

SSD for sure. Might want to consider the Patriot Torqz. Great reviews.

I'd bypass Vista and download the Windows 7 RC 64. Windows 7 is optimized for SSDs, Vista is not. TC is good to 2010 and will be released to retail 22 Oct. Vista is a waste of your time.

Graphics is more than just resolution, also consider frame rate. They usually trade off, higher res, lower framerate. It can make a big difference in playability. Stick with what you chose. It will alow some monitor upgrade headroom in the future.

Hunter315's suggestions are good, but this is a thread that's a month old.

most people would prefer to build cost effective computers and not throw money away so they get bragging rights .
A 4890 will be totally wasted on a 19 inch screen , so all it will do is push up your power bill
