That's what, a 2.66 GHz dual core CPU? For modern programs, the 805 should prove to be a little faster, but not by much. If you want to see a comparison, you can check some of the older CPU charts to see how they compare (charts from like 2005) 😛
i had a quick look is that a gateway system?? couldnt find any pics but i was able to run my 805 on a decent heat sink fan at 3.75ghz with only a small bump to the northbridge voltage and about .2volt to the cpu and at the time it could knock of the core2's. that was a long time ago. if you want far better performance without the heat and powerbill spend 50 bucks and get a e5200~e5300 will work on that board probably and almost get same performance as overclocked 805. spend another 30 bucks on a decent cheap heat sink and fan eg coolermaster hyper tx3 and you can run the e5200~e5300 all day every day at 3.5~4ghz far better option and it wont fry ur power supply if its a cheapy like with the 805 (i fried a cheap brand new 500watt ps on the first day with my sys at the time)
That board supports core 2 duos why would you even waist your time with a Pentium D. Look for a E6xxx conroe core it will run circles around a Pentium D you should be able to find one for under $70 if you look around.
e5200~e5300 will work on that board probably and almost get same performance as overclocked 805
An E5xxx would run circles around an Pentium D 805 the 805 would have to be overclocked to some astronomical number to even perform close. Netburst architecture was very in efficient and didnt really matter how high you overclocked it it would just be spinning its wheel and creating tons of heat stay away from the 805.
^actually Toms did a article on the 805 because of its relativley cheap price, low power use and heat output (it was after all the much better 65nm Ceadermill Netburst CPUs) and they OCed it pretty high.
And with that OC, it beat a Athlon FX and Pentium D EE. Both $1K chips while the 805 was $125-$150 at the time.
Hey Thanks for all the reply's. They were informative. I have another question regarding another mobo and the E5xxx. Both of the systems I am referring to are Gateways.
The other board is an Intel (Putton Bay) 945G Motherboard with a P4 3.2ghz HT. Will the E5xxx work on that one.
Thanks again.
