New Hardcore Gaming Rig

Well, you can build that if you like, it is after all your money but I must point a few things out to you:

#1 - Nothing lasts for 10 years, not even that. Think about 10 years ago, it was 2004 and people were still using WinXP. The Core2Duo didn't yet exist and the AMD Athlon FX64 reigned supreme. The GeForce FX-5400 was considered to be a powerful card and 1GB of RAM was the norm. PCI-Express was literally a year old and hadn't been adopted by the consumer-level yet so AGP still ruled the market. Most computers still had 40GB hard drives and larger ones were just starting to come out like the 160GB and the "monster" 250GB. Keep in mind also that all of these drives were IDE because SATA was still brand-new and wasn't yet cost-effective for the consumer market. With our technological advancements accelerating exponentially, I give that rig 6 years at best before it's considered a complete slug. Remember the Core2Extreme QX9770?

#2 - If you were to bank that budget and only get what is required to max out all games for the next 2-3 years, you could upgrade 2-3 times in that 10 year span and you'd have superior hardware each time. Remember that the tech industry is unique in the respect that things get faster, smaller and cheaper over time. In 5 years, you wouldn't be able to sell that rig for $300. Your power supply also probably wouldn't last that long either.

#3 - A hardcore gaming rig is just a PC that can max out all games without missing a step. To do that, you would only need to spend about $1500, or 1.5x the price of that absurdly overpriced CPU. I can max out every game on the market with tons of fps to spare. My CPU, video cards, motherboard and RAM cost me $1000CAD. That's about $114USD LESS than your CPU alone. I also didn't spend it all at once, I had the motherboard and RAM for over a year before dropping in the FX-8350. Almost 6 years ago, I got my first Radeon HD 4870 and the second almost 5 years ago before the 4870 left the market. I didn't change them because I was unhappy with their performance, I changed them because they didn't support DX11. In 10 years, we'll probably be on DX13 if we're even still using DirectX at all. You won't get a different gaming experience with twin GTX 780 Ti's than I will with my twin HD 7970s because they both max out everything. Therefore, my rig is just as hardcore as yours except I didn't flush money down the toilet to get it.

Now, having read all that if you still want to go ahead with this, by all means do so. If I've made you think twice, thank me. If your budget is $10,000 then spend $1500 on a monster gaming build and invest the other $8500. You'll be so glad that you did.
