At 1920x1080, you need at least HD7770. Take your pick among these options based on your cooling preference, budget. Performance should be the same across all models except for OC'd versions but I do not recommend those if you have to pay a prime premium because it is very easy to OC yourself:

By the way, you need to upgrade that power supply too to one that is at least:
■500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended
■600W power supply (or greater) with two 75W 6-pin PCI Express power connectors recommended for AMD CrossFire™ technology.
If you can afford a little more, say $155, then you can go for this instead:

But you need to up the power supply to:
■500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended
(600 Watt and four 6-pin connectors for AMD CrossFireX™ technology in dual mode)
