as the title says. i have this

System Manufacturer: Acer
System Model: Aspire X3810
BIOS: Default System BIOS
Processor: Pentium(R) Dual-Core CPU E5400 @ 2.70GHz (2 CPUs), ~2.7GHz

The pc is a slim line box so im not sure if any CPU will just go in it as im not to savvy on the internals of pc's or any pc. if any1 has the time could you plz link me to a decent upgrade at a affordable price around 150 GBP. i have 4gb ram and can make this 8gb if needed
thanks

I don't know whether it's possible and even a good idea to upgrade a pre-build system's processor. Even if it's possible, your E5400 Uses the LGA775 Socket which is already a couple of years old and isn't used anymore. So even if upgrading was possible, you wouldn't find a new processor that fits that particular socket. (Well, at least I haven't seen a vendor selling Core 2 Quad CPU's for a while now)

It is possible to upgrade the CPU on most pre-built units. You just have to do a little research to see exactly which CPUs are supported. Unfortunately it's not worthwhile in the OP's case. Save your 150GBP and work towards buying a new unit.

Sorry, but it's not gonna happen. In 9 cases out of 10 (pun intended) slim case means motherboard and PSU are probably not upgradeable. Your upgrade options are only another old crappy dualcore from 2007 like your current processor is, so it's not really recommended even if you get theoretical 20% more speed on top of your current system.

Rebuild is pretty much mandatory to get decent speed-up. You can probably reuse HDD from the current computer, but just about everything else needs to go.

thanks for the replys guys. saved me alot of messing around. just seen in a magazine the new alienware desktop x51 i think it is, for like 600.
thanks again

There's quad cores for LGA775 as well, the cooler just isn't gonna pull it.

I'm afraid it probably wouldn't work.

The case you have with the components inside, would hinder any cooling on a new CPU, any CPU worth spending money on will need some form of cooling, I doubt you will get a cooler, good enough to cool the processor inside that case.

Don't go with Alienware, overpriced rubbish. Can build the same machine yourself for 2/3 the price. Don't worry, if you don't know how to build one yourself, you can either learn (it's really wasy, the motherboard manual tells you everything you need to know), get somebody to build you one, or buy a ready built system (used), there are loads of legit ones. Just make sure it's on a respectable forum with a respectable member, i'd link the forum I use but don't know if such a thing is allowed.
