Re: Choosing between Intel and AMD dual cores...need help/info please..
1) The 6000+ is obviously faster, but not necessarily "better". I'd personally get the 5600+. At stock speeds, it's simply not worth it to pay ~$80 more for 200MHz, plus the 6000+ has more heat output (125w vs. 89W), meaning it runs hotter. I don't know about comparing them OCed; I think they OC about the same.
EDIT: I was referring to Newegg's OEM 6000+, I didn't notice the Retail was $60 cheaper. Still not worth $20 extra IMO.
2) The OCed E6420, simply because it's cheaper. Plus, you'd probably be running your RAM faster.
3) They are about the same at stock, dependent on the application. I'd say the 5600+ has a slight edge.
4) I'd go with the E6420. You have a better chance reaching E6600 speeds with a E6420 than you would trying to reach 6000+ speeds with a 5600+, IMO. And the E6600 beats the 6000+ in most, not all, applications.
ASUS A8N32 SLI-Deluxe, AMD Athlon X2 3800+ @ 2.8GHz, eVGA 8800GTS 320MB, 2GB Corsair XMS DDR400, 160GB WD HDD + 320GB Seagate Barracuda 7200.10, AC Freezer 64 Pro, 700W OCZ GameXStream, NZXT Zero :D
I think I've decided to leave... maybe I'll come back sometime.
