What is your rig Tok? In detail.
Asrock 970 Extreme3
Phenom II x4 965 BE 3.4 GHz (Going to upgrade to a FX piledriver when I'm done with the other things as the Phenom is bottlenecking my GPU)
Arctic Cooling Freezer 13 (Only aftermarket cooler that would fit my DELL motherboard, also going to upgrade to a Hyper 212 EVO soon)
4x2GB Kingston HyperX Blu 1333MHz DDR3
XFX HD 7870
BeQuiet Pure Power 630W Modular (Going to be upgrading later on due to cable-length issues with my case, this is an aesthetic upgrade more than anything else so it's low priority)
Western Digital Caviar Black 1TB SATA 6Gb/s
Xigmatec Alfar - With Window - Black With Orange Accents (Going to be putting some nice LED's in this later on, also an aesthetic choice so it's at the bottom of the list with my PSU)
Case has 2 of Xigmatec's own 120mm fans which match the Black/Orange scheme of the case and 1 really old Akasa 120mm that my brother found under his bed and gave to me, every little helps, right? Case has room for 3 more fans and I'll be getting them around the same time as my new CPU cooler.
Edit; Forgot to mention that I'm starting to think that my GPU issue might be with the card or the motherboard themselves, not with the drivers or my connection.
I dunno though, the most I've managed to find regarding my issue is some guy making a thread saying "Oh I have this problem with the HD 7870 and I'm pretty certain it's the drivers, I've tried everything else so I'm damn certain" and a bunch of other turbonerds saying "Oh you might need to undervolt it and underclock it and check the soldering on the PCB and maybe touch it up yourself, I know I've had a few situations where sucking a richard helped me out, blah blah blah" so I dunno, I might need to check it out on my brothers motherboard if he'll let me
