Hi, this is my first time posting here and I hope someone can help me. I have an HP Desktop Computer Pavilion 500-429. I want to upgrade the motherboard/cpu. I don't have tons of money so price is a factor. Any suggestions would be greatly appreciated. I use it for gaming and yes I know I'll need to upgrade the PSU also. So anything that will give me decent gaming power without breaking the bank and will fit in the case is what I'm looking for. Of course if nothing fits that description I'll have to buy a case.
