After the US election, I plan to double my rig's RAM up to 8 gigs, along with getting a different graphics card. I have a HIS 7750 currently, but I'm having issues with it at startup. It's like warming up an old vehicle. The monitor doesn't receive a signal until a few reboots have been done, then having patchy pixels/long vertical lines appear across the screen every few minutes, which are also solved by further reboots or toggling off/on the monitor. Afterwards, I am able to continue my session for hours on end. Unless I am unaware of any other problems this graphics issue may be causing, I have no immediate concern since I put it in expecting to upgrade later on.
Now that the time has come, what are some good graphics solutions for $180? For those wondering about my plans, I generally play games on a single 1920x1080 monitor. I have a 650 watt power supply, and my motherboard only has one slot for a graphics card, so SLI/Crossfire options are out of the question (though I don't expect SLI/Crossfire with only $180 anyway).
