I am just starting to gather information. It's been six years since I built
my last computer, and I have not really kept up with the latest
developments. I'm planning to build a new system for Windows 7, and would
like some recommendations regarding components. My new system will be used
primarily for Internet, e-mail, and home theater. I'm not really into
gaming.
For these uses an average dual-core system should be more than sufficient.
Home theater performance, specifically HD video, can be supported by
specific graphics cards and/or chipsets, so that the main processor is less
busy with that. From Intel the E5200 or the slightly more expensive E6300
are very good value for money. If you want some more processor power, the
E8400 would be an alternative.
As for AMD, the 4850e or the 7750BE are good value-for-money options.
Combine that with a AMD 780G/790GX or Intel G45 motherboard with HDMI
output, and you have a decent kit to built a pc capable of blueray
playback. For this use it might be worth investing as well in a low-noise
cpu cooler and PSU.
In case you really need much more processing power, such as for regular
video encoding jobs, you could consider the cheapest Core i7 model, the
i7-920, provided your software supports multi-core processing. The other
models of that series are IMHO still overpriced.
