The 4850e is about twice as fast as a Sempron LE 1300 and and one of those is about twice as fast as an Intel Atom. You won’t be able to play any recent games but emulators and 1080p video should run fine.

A 65w processor will be pushing the PSU to the limit so go with the Sempron, or try and find the 4850e online.

I am plannig to build an HTPC with a similar configuration. Unfortunately I failed to find an e-series AMD Athlon CPU(e.g. AMD Athlon X2 4850e) in Turkey. I now have two alternatives;

i. A Sempron or single core Athlon CPU with low power (i.e. 45 W)consumption,or,
ii. An Athlon 64 X2 DUAL 5000+ 2.6GHz CPU or similar with a moderate power (65W) consumption.

Which one would you suggest?

With the first alternative, is it possible to have a satistfactory HD (1080p) movie and some gaming performance,

With the second alternative, is there any risk of power supply problems.

Thanks for the attention.
