800 MHz FSB seems very slow?

[Retro6]

I want to upgrade the processor on a Dell OptiPlex 745 that is cost effective to the maximum processor I can put into this machine. I have googled what the maximum specs I could upgrade this machine too but I can't get a straight answer. It takes a T type or 775 processor. I might even be able to get a quad core in there. Quad cores are expensive in terms of upgrading this particular machine as its seems crazy to be spending 50 70 pounds on a processor for a machine that is worth about 20 quid. It has to be cost effective. The current processor is 1.7GHz dual core and is very slow.

I found a 3GHz dual core processor E5700 but only has 800 MHz FSB. The processor was under 3 pounds so cost effective for this sort of machine but I wonder if it would make a huge difference with the processor only having 800 MHz bus speed?

Thanks for the info everybody. Perhaps its best to fit the 3GHz dual core as a Quad core is not only pricey but will get hotter and the PC is only a small form factor witch is quite compacted inside. This may have to be a Windows XP 32bit old games PC / light Linux dual boot system. So the E5700 3GHz dual core 800MHz FSB is the highest processor I've found at under 3 pounds I think its a worthy upgrade and better than the slow 1.7GHz dual core processor it currently has.

Pricey? Q6600 is 5 quid delivered. If you cant stump up the cash for that then no point doing anything

Wow excellent 5 quid? I've had a look and there about 10 quid or there abouts. I will order one.

Which won't work in his laptop.

Its a desktop.

10 quid gets you a q9550

Prices must have doubled. There 20 quid upwards.

Of course it is, that's what happens when I am upgrading a Dell laptop for my son while browsing the forums. That cpu still won't work. Like I mentioned in post #5, the Q965 chipset is not compatible with 45nm cpu's.

The Q6600 is right? cex has one for 4 quid.

What isn't compatible with this machine will work on another LGA775 board. I have a few I'm going to be upgrading but the first one to be upgraded will be the OptiPlex 745

Yes the Q6600 will work fine as it's 65nm. Any 965 or 975 chipset will not work with Yorkfield and Wolfdale 45nm cpu's (there may be a couple of high end board exceptions plus Asrock had a habit of launching "Frankenstein" boards). The P35, P31, G31, G33, G35, and X38 chipsets were the first to officially support the new cpu's.

Thanks for confirming. I've a few computers that have socket 775 gigabyte boards I think I have at least one with a asrock board.
