I have a currently non-functioning gaming computer which had a critical failure (I think I fried the CPU). I was thinking of replacing the motherboard, which would cost me about $150, but I wonder if this is really worth while, the computer is about 4 years old and wasn't exactly top of the line when I got it (2 gigs RAM, 500GB hard drive, AMD Anthlon dual core processor, 512mb ATI Radeon Sapphire graphics card) and I figure it would be due to be replaced soon anyway. Would I be better off just buying a new computer?
