My current situation is that I am running x-plane 10 on a standard 2008 macbook. It is now at the point where it can hardly handle WED. After only owning Mac's beforehand I looked at building a PC. I found that it is even cheaper than I thought to build a powerful system. My only problem is that I have very little knowledge of computers, I have done some research but I know that there are some very knowledgable people on these forums who could give me some advice and guidance (I'm not even 100% sure the parts I grouped together below will be compatible). This is what I came up with... Is it overkill? $2850 Australian Dollars (almost parity with the USD). It may seem like a lot but I payed $2,200 for a macbook 13" back in 08 My questions: Something I don't understand is memory. Would it be better to go for faster memory but 16GB instead of 32? Also what do you think of the GPU, as far as I know it is arguably one of the best variants of the GTX 680. Are there enough PCI (another thing I don't understand) slots on the motherboard for everything? Is 1000W enough power? I intend to overclock the CPU. Thanks Andy
