Im currently planning on getting my job to upgrade my computer, having changed from building computers to just managing software im a bit behind on all the new stuff.

Whats the ups and downs on Dual / Quad Core? Whats recommended, whats needed and why are the processors only around 2,4 - 6 if its quad core?

What graphic cards are the edge at the moment?

Phys cards? are they really needed?

Any mainboard recomendations? If always been quite happy with Asus, but Abit has proven good to me too!
