(Computer listed on my profile. Don't judge me for having an hp desktop; it was cheaper than building my own computer for even near the power I have now.)

My resolution is 1920 x 1080.

I've been pretty disappointed with my computer's gaming abilities. Skyrim runs pretty POORLY, and I'm FAIRLY certain it's because of my awful GRAPHICS card. Now, I don't expect to be running it on very high or anything, I just want a basic upgrade. My card should be performing on high (according to Steam), but I can't even get it to perform well at medium, which should be easy for this card. In the experience index, my graphics are rated at a 4.9 and my gaming graphics at a 6.3 (this is how I know this rating system is garbage).

Requirements:
I would like the price to be under $100, with shipping. I'm not looking to have the most powerful. I want decent.
I don't want to have to install any other FANS. If it has heating/cooling problems, I'm simply not interested.
If the card has a ton of troubles with older games (KOTOR, Diablo II, Icewind Dale, etc), I'm not interested.
I don't want a card that is more powerful than what my processor/ram can handle. This upgrade is to make my computer usable for another 1- 1.5 years before I build my own.

Ideas:
I'm thinking maybe the HD 5550, which would obviously be a small upgrade, though it's supposed to outperform the 6450 by quite a bit.
I've also been thinking about the GeForce gt440, which would be an actual upgrade and give me a THOROUGHLY decent card.

So what do you guys think? Which card would fit best with my computer? Or, if you have other ideas, I'd be happy to hear them! Thanks so much =]I'd go for a Radeon 6670. That would cost you about $80.

I ended up spending like 109 with shipping and a one year warranty. With the mail-in rebate, it should be about $89. Thanks for your help.

I'll post again when I get it installed.It works great and looks beautiful.

Truly, you are a hero.
