Hi , I have a 8350 and a M5A97 le rev 2.0 motherboard......all is working okay , but the 2nd graphics card slot only runs at 4 x which is how Asus made the board....plus when over clocking i seem to suffer with droop on the vcore.

Ideally i would like a good overclocking board with 2 fast PCI-E , so i can consider crossfiring , but ideally at a good price perhaps less than £60.00 as this will be a bit of a sideways upgrade until i get a 2nd 280x....i will of course sell my old board on eBay which should fetch around £30 - 35.00 after fees and shipping etc.

I am based in the U.K so ideally so well priced MB's available in the UK please.

I have a good solid xfx 750 watt PSU

you are making too much of needing 2 x full speed slots - only the 990 series like blackbird has posted with pcie-x3 slots do this.
even with a 16x/8x or 16x/4x setup your going to lose a max of 10% in theoretical throughput - in the real world this equates to between 5-10fps on a crossfire configuration.
This will not matter to you in the slightest as an 8350 ( even at 4.5ghz+) is not enough to max a 280x crossfire setup out - an overclocked intel k series will barely do that.

your main problem is running an 8 core fx on an asus LE series board - its a poor poor board & barely adequate for an 8 core at stock clocks & is well known to throttle an 8350 at stock speeds.
either the msi gaming baord listed above or the gigabyte ud3p below are far better for an 8320 & will have no limitations when it comes to overclocking.
