Alright guys, question for you.
So once again I'm looking at a GPU, but I actually have the money now thanks to my job. I want something in the <$150 range but I'm not sure what I want to get. I've been looking at these:
AMD Radeon HD 7770 1GB ($130)
Nvidia GeForce GTX 650 Ti ($150)
AMD Radeon HD 6850 1GB ($140)
AMD Radeon HD 7750 1GB ($100)
Now the last two are a bit of a stretch since they're over $130 (I'd ideally like to stay at or below that) and the 6850 is a last gen card that from what I've seen of it is pretty noisy. I'm only considering the 650 Ti because it's Nvidia and I'd love to try them again, also because Big Picture Mode supposedly has problems with AMD cards under Windows 8, which I'll probably be upgrading to. I'm going to be playing at 1080p with medium-high settings. AA is a luxury that I rarely use much of (usually 2xAA).
The 7750 is probably something I'd go with since it's the cheapest and according to Tom's Hardware it has some decent performance at 1200p with lowered details.
What's my best choice?
The reason my budget is so strict is because I don't want to starve myself, I need gas to get to school and work, and I'm planning on other upgrades as well (new HDD, an SSD, Dual 1080p monitors).
Edit: I should also mention I'm pushing a 460w PSU. Could it handle it? My current card requires no extra power from the PSU, everything is supplied from the PCI slot (another reason the 7750 is looking appealing to me)
