Need advice, overclock/crossfire or not? + possible bottleneck?
I recently had my 9800gt die on me, and after some research I decided not to spend on a new build or get a replacemetn 9800gt, just upgrade what i already had. So i ended up getting a new motherboard (asus pq5 pro turbo) so i could overclock my q9300, and a HIS Radeon Iceq5 turbo 5770 because it seemed like a pretty decent card for the price, and with the new mobo i could probably crossfire another one later on. I also got a new 550 watt psu and a new case with better airflow.
What i didnt realize though was that the mobo's 2nd pcie slot is at 8x link, and after some research online it seems that the q9300 isn't very overclockable.
So i was wondering if anybody could give me some advice on how to squeeze as much power out of this setup since i dont want to spend on a new build for at least another 1-2years.
Is it worth it to crossfire even though the second card will run at 8x link? Is my q9300 a bottleneck for the 5770 and vice versa?
I will mainly use this for gaming, watching movies and some web browsing.
Full specs are: Q9300 Quad core @2.5ghz (w stock cooler) 6 gigs ddr2 2x 2gig 2x 1gig (not sure what brand, grabbed them out of a gateway fx4710) Asus PQ5 Pro Turbo Motherboard OCZ Fatal1ty 550watt PSU 640gig WD HDD@ 7200rpm HIS Iceq5 Turbo HD Radeon 5770 (oc'd using ati overdrive to 900/1350)
Any advice would be appreciated, thanks in advance!

x8 PCIe slots are fine. There's no discernible difference over x16 slots with a single GPU card.
