Help with config

guys i`m buiding a new system ........ my preferred configs are


1. ga ex58 ud3r or msi x58 pro e
i7 920
3 gb corsair
asus 5770

2 . msi gd65 or dp55wg
i5 750
4 gb corsair ram
asus 5770


i have rest of the things with me......... i only have a 20" screen so i suppose a higher card will be unnecessary ,,,,,,
don`t worry abt the brand of the ram ......... just the amount ........ i am on a budget build ...... so thats why i didn`t go with 6gb in the first ................i`ll be replacing the 3 gb with 3x2 gb within 6-12 months ....... and might add another 5770 next year or so.......... have a 650w corsair psu ........

comments are highly appreciated.......thank in advance

What will you be using this system for? I assume gaming. In which case 4GB is plenty, so you could keep some dough in your pocket by going for the i5 750 system and only adding a second card, rather than having to shell out for more memory as well.
If it was me I'd go for the MSI over the Intel board.

I think you have overestimate the power requirements of those cards. The way I figure it is 100W for i5, 110W for each 5770, totals 320W just for those three, then 100W for any other components, which is 420W. And that is on maximum load which surely it won't be quite that high very often, but even so it's 65%.

I think they perform similiarly, and unless you keep a table (like I do) of all those little specs it's hard to keep track of. So it's an understandable mistake to make.

ASUS Sabertooth 55i - $195 shipped
ASUS P7H57D-V EVO - $208 shipped, also has USB 3.0 and SATA 6Gb/s
EVGA P55 SLI 132-LF-E655-KR - $180 shipped, $35 MIR
GIGABYTE GA-P55-UD5 - $200 shipped

I recommend the P7H57D-V EVO. Sure, it'll take you $8 over budget, but it not only gets you Crossfire support, it nets you a couple USB 3.0 and SATA 6Gb/s ports. I'd say that's worth $8. Think about it, that's... a movie ticket; breakfast at Denny's... or a couple gallons of gas, depending on where you live.

Hmm... I'm sorry I missed that one earlier. It looks like a pretty good option, especially at $160. Per MSI's product page, it looks like it will support the 8/8 setup you're looking for, not to mention it'll satisfy pretty much everything else you're looking to do. And it's garnered a good collection of positive reviews.

I'd do it. Go for it, and good luck with your new rig
