System usage: mostly gaming, maybe photoshop or video editing, but primarily gonna game and watch movies on it
Prefered website: newegg
Overclocking: maybe

i mainly need help on the psu, is that good enough power and would it fit in my case?
heat issue wise, should i buy some extra fans? if so what kind?
Is everything compatible with eachother? for the most part i think so, but im not positive and would like a confirm

What I was writing or the other thread :

Thanks for editing that OP

Thats a good build . And the case is really interesting. I havent seen it b4 . I have a silverstone TJ08 and like it a lot . The sugo seems to solve a lot of the airflow issues with two large fans at the front . Its clever .
Toms system builder marathon is building a m-atx system right now . Article soon .
They are going to use an m-atx sli board from evga [ I think ] , but theyre also using a much bigger antec p182 mini thats as big as some full atx cases .

Definitely use a modular psu . There just isnt room in small cases for all the extra cables . I used an Corsair HX 620

The only other suggestion is that I'd probably use a 4890 gfx card because I like ATI's ccc better than any nVidia software

Just keep an eye on temperatures and if there room for more fans then I'd install them

Yeah the HX 620 is expensive in the US , but here for some reason I got mine for about $80 US .

ccc is catalyst control center .
You have direct overclocking options, fan speed options etc . It allows you a lot of control and gives you feedback about temperatures of the gfx chip etc . Very nice compared to the nVidia drivers I was using last year .
Maybe theyre better now?

The 4890 is new so all the cards are the reference design and all identical . Buy the cheapest one , or the one with the best game bundle
Search on newegg for ati 4890 and theres a powercolor for $219

Theres a review

and I think theres an article on anandtech comparing the gtx 275 and 4890

PS those are both fairly big cards . Do you know they will fit in your case? If theyre longer than the mb is wide they might not

you should look into getting 2 4770's to crossfirex. it will cost less than a gtx 275 or a 4890 and will perform better. read this th article http://www.tomshardware.com/review [...] ,2288.html

would be my recomendation. you can get some for 99.99, however the only one that comes with the crossfire bridge is the xfx (they are about 10 bucks each, so that negates your savings).

thats not a bad psu, but its a low efficiency psu, which means it will be hotter than a more efficient one. there is more than enough power on a quality psu. so long as your over 35 amps on the 12v rail you will be fine powering the 955, and 2 4770's, even overclocked. that is if you have a stable psu.

i'd recomend

or if you need modular

or
http://www.newegg.com/Product/Prod [...] 6817171036

two 4770's, with a tdp of 80w each, and the 125w cpu gives you 285 12v watts, or 24 amps there. the smallest of these psu's has 35 amps on the 12v rail. all are stable, and efficient. even overclocked, your system won't use more than 325w on the 12v rail. the smallest of these has 35 continuous amps (420w) on the 12v rail.

the rest of the system seems very good. this should put you a little lower on price, and will be a more satisfactory system.

how exactly were you proposing a crossfire system would work on a m-atx mb?

crossfire needs 2 pci-e x 16 slots on the motherboard so both cards can be installed .
Who knows? , maybe there is a cf capable m-atx mb for phenom but the biostar you are looking at isnt one .

Since you have one gfx slot then you have to use a single card . That xfx 4890 is a great choice

you dont need crossfire .

The single 4890 is roughly the same gfx output as two 4770's .

i read core 2 duo is better for single threaded and phenom better for multi threaded? but are they releasing games that are multithread that would make me get phenom over the cheaper intel? i heard intel would also be much cooler

ah so the 4850x2 would fit on my mobo and not need cf board or w/e? assuming theres actual space for it

Updates have a reputation for not being as miraculous as microsoft claim .

Id be doing a clean install of the new os .

Id probably head straight to the RC of 7 for a gaming build [and didnt have business critical files] , but that will definitely mean a clean install next year since you cant update the RC .
If you get the right version of 7 you can also run xp at the same time so older apps will still run perfectly
