Is there a budget? or just cheap as possible?
Yes. And then again. No.rather get Stulid's suggestion, IIRC P55 is a better chipset than H55
Yes. And then again. No.
You get two less USB ports, SLI or CF is not going to happen (but one card will run just as well as on a P55).
At the cheap end of the motherboard scale none will be amazing overclockers but that's not the aim, it will work as needed, to run the 750 at stock and have 8GB ram.
That chart is meaningless.
All it shows is some unimportant features that no-one cares about.
The only interesting thing on there is the pci lane configuration, even that depends on the P55 board in question.
Is there something incompatible with the Gigabyte GA-P55-US3L Intel P55 (Socket 1156) DDR3 Motherboard [GA-P55-US3L] at £82.99?
I'm not an industry expert, what do you know the P55 will do that the H55 won't that will benefit a stock 750.That chart is meaningless.
