Ok guys here's the problem I've got an All in One Sony Vaio VPCJ1 and have pretty much run out of upgrade options have already fitted an SSD maxed out the RAM with 8GB and changed the old CPU i3-310m for an i5-502m I could go up to an i7-740m but theres not a huge advantage and the built in GPU will still strangle the system as it's not possible to turn of the NVIDIA GeForce 310M that's built in so my question is do you know what alternative motherboards there are that will be compatible with the all in one chassis ? hope that all make's some kind of sense
