planning on getting a Q9300 http://www.newegg.com/Product/Prod [...] 6819115043

Was looking at this Mobo, GIGABYTE GA-EP35-DS3R LGA 775 Intel P35 http://www.newegg.com/Product/Prod [...] 6813128086

Has everything i want for a decent price, But is it a good choice?

Well, this board has one of the best options for de chipset but not the best in the powe phases for a Quad Core processor.
I would go P35 DS4 or higher or ASUS P5Q Deluxe or Premium.

how do you determine power phases? i would like to do some more research into this, can you explain how to know whats a good board in terms of power phases? Thank you!

after considering your reply ive come across this for 200 bucks,
ASUS P5Q Deluxe LGA 775 Intel P45 Intel Motherboard

The mobo you just listed is a good mobo for overclocking and should be fine.

If you don't want to overclock much beyond an FSB of 400MHz, the EP35-DS3R is good. I have it stable at 400MHz with my Q9450. I can't really get it stable much beyond.

this one is the best

hmm i think i like the asus the most, but ive been going back and forth between the q9300 and e8400.
