MOBO HELP!!!!

Hi i just bought a 4870 i flashed it with the asus bios and love it but i see that my prosser (E6700) is bottlenecking so i tryed to overclock but my mobo (4CoreDual-VSTA) is really bad even 10 mhz and crash i need help finding a mobo because there are so many chipsets i dont really understand what chip set is good at what . i am a collage student so simply upgrading my cpu is not easy as money is very limited
current specs
processor: E6700 at 2.66ghz 1066MHz FSB
Mobo: ASRock 4CoreDual-VSTA
Ram: OCZ 2x1024MB DDR2 PC2-5400 667MHz
PSU: Antec TPQ-1000 1000W
HDD: 2 Seagate 320gb (raid 0)

so basically i want to update my mobo i want a mobo that can
#1 keep my current cpu (E6700 at 2.66ghz 1066MHz FSB)
#2 Keep my current ram OCZ 2x1024MB DDR2 PC2-5400 667MHz
#3 I would like to add another 4870 later on so a board that can crossfire
#4 easy cpu overclocker (since i am a noob at cpu overclocking)

also i would like to grow in this mobo later on so 1066ghz is nice for now but i will update same goes for the ram 667ghz is nice but i will update so growing room is nice

also i was wondering if my current hdds are ok or should i get 1 raptor?

any and all help is really really appreciated thanks

P.S. i do have desent cooling. I dont think the reason my overclock all ways fails is temps its just that this mobo is terrible

the p5q e or deluxe would be a great upgrade for you

im looking into Asus P5Q Pro which can be had for 140 from the egg w/ free shipping currently and would give you the xfire option and some head room for growing
