Tbh a 590 is overkill for 1920x1080 (and it's not really that great a card - great performance figures aside, it has has inherent design faults and is a slave to drivers like most X2 cards. It would also be bottlenecked by the CPU running at stock clocks)
A single 570, or even a 580 (budget permitting) would suffice.
As for OCing, it depends on the game and how much eye candy you want.
ie My 580 handles most games smoothly, although there are the odd few that do benefit from an OC (I like candy

)
I've got a 570 in my X58 rig and it seems to do okay, although it's paired up with a 22' @ 1680x1050 - I haven't really tested it at 1920x1080, but I suspect the odd OC here and there wouldn't hurt.
For the best 'budget' performance boost, a 570 + an aftermarket CPU cooler with a CPU OC would give you a noticeable performance increase.
