APPROXIMATE PURCHASE DATE: black friday/cyber monday BUDGET RANGE: $600 After Rebates

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: photoshop, general internet surfing, watching video, casual games

PARTS NOT REQUIRED: keyboard, mouse, monitor (for now), speakers, OS

PREFERRED WEBSITE(S) FOR PARTS: newegg.com, but I'm not opposed to making the drive to frys or microcenter in Chicago if the deals are worth it

PARTS PREFERENCES: Intel i5

OVERCLOCKING: Maybe SLI OR CROSSFIRE: No

MONITOR RESOLUTION: Don't know, but I'm pretty sure whatever computer I build will work for now, but I want to upgrade to at least a 23" down the road.

ADDITIONAL COMMENTS: I'd like the rig to not be a power hog and be relatively silent. I'm not big on lots of extraneous glowing lights on the case either.


I've finally got the go ahead from the "spending committee" to build a new computer. If there anyone knows of any good deals over the shopping holidays I'm all ears. I'm ready for a roadtrip, if need be, down to Chicago if the savings are worth it. I've got a friend who will help me if I get stumped during install.

Trying to figure out all the graphics cards is making my head spin. I'm not a gamer so I haven't kept up with that.

This is mostly a general use PC that I'd like to be upgradeable for a while and keep the power consumption to a reasonable level.

Reading here has helped a lot, but I'd appreciate some options from people who know more than I do.

Thanks!

Oh yeah...I don't know if it matters much, but I'll probably use it to stream content via PlayOn or PS3 media server too.
