Let's take a quick look at some of the features the 3800+ has to offer:
Some details about our motherboard and BIOS settings
The Athlon 64 3800+ runs by default, at a speed of 2.4GHz, the same clock
speed as the FX-53. With an L2 cache size of 1024KB, the FX processor overshadows
3800+ performance-wise, with the latter having no extra features to make up
for it. Instead, it's built with a locked multiplier that would probably
disappoint most overclockers.
However, the 3800+ ships at a price of only $660, a lot less than the cost
of the FX-53 (around $850), making it the best buy between the two.
