Hi guys,

A few months ago I bought a Dell Optiplex 755 (Intel Core 2 Duo 3.0GHz, Windows XP, 4GB DDR2 RAM) and I believe it has a 270W original PSU. It came with an ATI Radeon 2400XT graphics card, which has 256mb memory and a core clock of 700MHz. However, the card is DDR2.

Now, all was fine until a few days ago when I replaced my 19" monitor (1280x1024 or whatever it was) with a 22" widescreen (1680x1050). When I did this, I began to experience problems as listed below:

1. "Virtual memory too low" message
2. Horizontal lines across screen moving up and down when I have a white background up. Is this called "tearing?" I changed the vsync but sometimes the problem still returns
3. Lagging in my game (Flyff, a F2P MMO) that wasn't there while using the 19" screen. I can tell that my game is having difficulty with this larger resolution.

So, guys, here's what I'm looking for:
- Can run on my 270W (lol, I promise I'm not a troll, this is a REAL question) PSU
- Is "low profile," as my computer is a slimline
- GDDR3 or GDDR5
- Has a faster clock rate than my current card (so more than 700MHz)
- Under $100

Any suggestions? Thanks.

HD 7750 (stock clock of 800 MHz...some cards are overclocked which is not good for sub 300 watt power supplies) or HD 6670 are commonly recommended for 250-300 watt power supplies.

You still may need to upgrade your power supply if it's not a quality one. Here's an example of a good quality one that fits slimline cases:
