Hi guys, I've been a reader of the TH for a while and decided to venture into the forums to seek some advice.

I am upgrading from an ancient P4 now that I have a steady job once again. The new computer is going to primarily be for gaming. My current wishlist was to go for an I5-3570K with the ASUS Sabertooth but I'm open to changing out that board for something that can do x16/x16 in 2-way SLI if I stick with that CPU.

The real question is, since jumping to any CPU will be a huge upgrade from my current one, and I'm still getting my parts together...should I go with the 3570K, some Haswell flavor, or wait for Ivy Bridge E?

The E processors are the only ones that will give you that dual x16 for the SLI of the video cards and if you go with three in three way then you get X16,X16,X8. I can verily that because I have the i7-3930k and have three way SLI and that's what it reads in the bios in the GPU simulator.
I would wait for the Ivy Bridge-E as that will have the native Pci-E 3.0 on the CPU. The E processors have 40 lanes of Pci-E bandwith and that's why you can get the true x16 for both slots when in two way SLI. Your regular CPUs have only 16 lanes of bandwith and that's why you see the motherboardsay x16 x0 or x8,x8.

I would go with either a Haswell processor or Ivybridge-E. The extra cores on Sandybridge-E are very nice and with the next generation consoles sporting 8 cores each, we're going to see some very heavily threaded games coming out, which should propel the LGA 2011 processors much farther ahead than they already are

I believe you have a point, but if that's the case, he'd be better off looking at the Amd "8" core Cpu's. The 8350 isn't a bad Cpu in and of itself, it just doesn't fare as well against the I5 in games right now. Going forward though, everything you brought up points to a major resurgence for that Cpu. I'd avoid the IB-E Cpu's simply because of their price. That's a lot of money to spend on a Cpu just for gaming. We'll see how things pan out though with games after the next gen. consoles debut and we start seeing console to pc ports.

True enough. I'm currently planning on getting the CPU, mobo, and RAM last so chances are that prices will come down a bit. I'll read up on a few more articles but it may end up being an I5-3570K. Thanks for the input so far!
