If you wanted to build a computer that does primarily gaming but would also do some fairly intense rendering with autodesk. I need advice on which one I should buy. Money is a very serious concern and with a xeon I would also have to buy a gpu and a heatsink. But I would run into the consideration that between all of the things i would have to buy it might run into that an i7 4790k would be almost the same price as the xeon. so for price what should i get. a 4690k, xeon e3, or the 4790k. Or would it just be a better deal to buy a discreet gpu that would actually be adequate for gaming as opposed to a gpu that simply tries to rival intel hd, for the xeon.
I'm not sure what this "B" version is but my E3-1231 V3 came with its own heatsink and fan (which I'm told is better than the stock i5/i7 ones) though I use Hyper 212 Evo cause it's cheaply available. This Xeon is really a refreshed i7-4770K without the iGPU, overclockablity and 100MHz less clockspeed. As such, its performance is great for gaming and rendering/editing works. I've very little experience with the latter so I do advise you look into it yourself but I've read positive feedback all over the Internet.
Regarding a discreet GPU, wouldn't you need that for rendering and gaming anyway?? I don't think the Intel HD graphics can match a dedicated GPU. Imo, Xeon + H97 mobo is cheaper than 4690K or 4790K + Z97 mobo + an aftermarket cooler which is required for overclocking. If you're not interest in OC, no point getting the 'K' CPU. For gaming only, i5 4460 or 4590 will do but because you talked about the rendering, I think the Xeon would be a better choice.
Obviously, the i7 4790K is the best (in terms of raw performance) out of the listed 3 but it's also the most expensive.
