700-800 Basic Gaming Rig

[armless]

Hey guys my cousin recently asked me to help him build a computer for basic school work and he wants to play some games. I know for sure the main game he wants to play is League of Legend. His current budget is about 700 dollars and he is going to be using a 19 inch monitor.

Here is the league of legends specs

I haven't been reading up about computer parts recently so I wanted to see if these parts are compatible. Any suggestions would be nice.

Motherboard: GIGABYTE GA-P55-USB3 LGA 1156 Intel P55

Will this PSU power everything and anyone have any experience with it?

He is going to be using a 19 inch monitor only. Is this card good enough or is it overkill for a monitor of that size?

Thanks!!

OCZ ModXStream Pro 600 W Power Supply Review
Plenty of power for everything in your planned system.

HD 5770 is a very good match for a 19" (1440x900?) monitor.

Your build list seems to be missing a DVD burner and the operating system.

Any room in your budget to move up from the dual core Core i3-550 to quad core i5-760?

Some reworking I would do including a switch to AMD, imo a better value.

MSI 880GMA-E45 ($43 less) AR
AMD Phenom II X2 555 +$5gift ($40 less)
Western Digital Caviar Black WD1002FAEX 1TB ($40 more)
Patriot G Series ‘Sector 5’ Edition 8GB (2 x 4GB) ($17 more) AR
Radeon HD 6850 +$10gift (~$35 more) AR

I couldn't decide on the specific 6850 and I didn't touch the Case & PSU.
Hopefully you could unlock this CPU to a Quad.
Overall at this price this is what I'd do, you may do as you wish but I thought I'd give you an alternative.
