Hey, im building a franken-puter, and i have one that has a dual core 2.8 ghz processor, but less room to upgrade and some other unsavoury things, and then a different computer with a single core 3.0 ghz processor, with better expantion slots and such. I dont have money at this time to get a new mobo or cpu or anything, so i was wondering which one (in your opinion) i should go with...
the two base computers im working with (upgrading things like RAM, HDD, and graphics) are a Dell XPS 200 and a Dell Precision TM Workstation 370
Thanks!

Hi!!
I would still go with the old dual core cpu.Because it might get the work done faster
What is the CPU brand and model?

Go with the dual core since it will be much faster for parallels, multi-tasking and general computer usage. It also probably has more instructions per clock making it faster even with single threaded applications.

While the dual core doesn't have the same expansion capabilities, it would be better to have since a second core will help in workloads.

And if I remember correctly, the Pentium D 820 (your dual core) was a favorite for its cheap price and very high overclocking ability.

I would go for the Pentium D 820 over the older Pentium 4. Load it up with 4GB of RAM and if possible, install Windows 7 Home Premium 64bit. Will run very nice.

Would i need a 64bit system for the 4gigs?

Well,
Yes and no.Currently with most 32bit they dont support any ram higher than 4gb.

^The other is a Pentium 4 w/HT.

Both are LGA775.

^I was talking to the OP. But the Pentium D820 is a 64bit capable CPu:

http://ark.intel.com/Product.aspx?id=27512&processor=82...

Intels 64bit started with the Pentium 4 5x1 series based on Prescott.

And to the OP, yes you need a 64bit OS to fully utilize all 4GB of RAM. Without it, you can only use 3.25GB to 3.5GB due to 32bits limitation of only 4GB total RAM (meaning system RAM, caches, GPU RAM) which all adds up. If you ahve a 1GB GPU then normally you get 3.25GB of system RAM. If you have a 64bit OS, you can support well more than 4GB (Something like 16,000 Terabytes of RAM) so it doesn't matter.

So.... go with the dual core?
and one final question, what would I need to find out in order to move CPU's around, for instance from the XPS to the other one?

I already looked it up to see if you can move the Pentium D to the Precision 370, unfortunatley the 370s mobo will not support anything above a Pentium 4 3.8GHz (the 630 series Pentium 4 CPUs).

And due to Dells proprietary nature (the 370s mobo even uses a 925X chipset which was only for them) I don't think you could do a mobo swap. Dell likes to make it so you have to buy a new machine.

thanks a bunch. now i have to figure out which ones to use, because i was going to put a wireless card in, but the XPS doesnt have any sort of expansion slot other than the one for the graphics card.
