Another vote for selling it all off and starting over. Return the whole unit to Best Buy if you can.
You will be 1000x happier just going big right away rather than trying to shoehorn that thing into gaming properly
I agree but well, I've seen this thread 1000 times before on the internet. The OP will NEVER take the primary best option and usually takes the secondary less optimal option. Almost 100% of the time. Not sure why it almost always work out that way but it does.
I think when the OP posted that he had a 1k budget it was more out of anger than anything else. I highly doubt he ever had an intention of spending much of anything and was in fact looking for that bandaid fix solution.
"Budget" online rarely means thte same to everyone. For me, 1K meant "I'll spend up to 1K but I'll spend more if anyone gives me a remote reason too." For other people, 1K is a HARD budget, and for others, it's "Up to 1K but please, give me the minimum possible!" So all depends.

It also depends on what you want your gaming experience to be like. I don't game OFTEN at all. I only been gaming recently since my little bro was home for 1 week. Otherwise, I've played Bioshock (The first one,) Tomb Raider, BattleField4 and Dota 2 so far on my rig. I'm getting close to a year.
Even though I don't game often, I'm happy when I do game. I'm happy at never having to worry about whether a game can be run, or worrying about FPS choppiness/lag. When I load up a game, it's buttery smooth no matter what. I NEVER have to game below 1080p which also makes me happy.
So it depends. Some people are happy with Xbox One type graphics. I think OP can achieve that with a 750Ti upgrade. I think for us on this forum, it's obvious about what you do. But for OP, it's different about what he can be happy with.
