Well that's weird...I have HIs Ati Radoen x1550. It is an old pci card for my dell. The card is great for ocing. I bought a big fan, it barely fits in my case for good cooling. I oc it olny for gaming. The stock speeds are : Core 555.04 and memory 395.6 I think. I oc it to 650+ 415+ for gaming, I play need for speed carbon, I have 800x600, all medium, car it maxed, reflection too. And I have 28+35fps on it :d This car dis great for ocing. Last week I did 740 core and 450 memory I played css on all maxed out everything, the card will let me take anti aliasing 6x on 1280x1024 and I had 23+48fps. That was max but normally to cave the card I play on 800x600 all high except I have models on medium, the game looks great and I can't believe its an old pci car. I bought it on newegg. Ow when I oced it to 750/450 the card temp was good, after 20mins of playing when I touched the core fan it was really warm, not hot but warm so I oced it down and went to lower resolution :d Sorry but no programs support my motherboard so I can't read temperatures except my hard drive

I use my hand for that. I even make movies while playing css :d I will send u link I had it oced like 650/ 415 that's my normal settings for playing and then I clock it down....
