So after no luck from anyone on the LTT Forum I will bring my question here.
I need to find a cpu & motherboard with the remaining budget of $330.
The problem with that is I don't know what cpu would be good for a 3 way 7950 crossfire setup I'm doing.
I already have everything else but I still haven't decided on a cpu...
I looked at the 1st Gen i7 & Six core 5670 Xeon but I have no clue if that is worth getting.
I'm in need of major help!
Thanks guys!
older parts are more expensive because they are no longer manufactured... you could get a 4690 and decent H97 board... but american horror story is on and I am a slave to it...
www.pcpartpicker.com check out the 4690nonK/H97 and 8320/990 boards
Everyone on the LTT said anything AMD is a bottleneck...
That's why I looked at the 1st Gen i7.
Depending on which model you look at , I can get a combo for $220 - $240.
But I will check out what you linked!
Well LTT is a hotbed of nVidia and Intel fanboyism. An 8350 especially overclocked will be fine.
Going with a 1st gen i7 is probably a bad idea. It would most likely be slower than the AMD and you'd be on an even more ancient and outdated platform.
I'd go with the i5 or a Xeon 1230V3 or the AMD.
there is no Bottleneck when it comes to the FX 8350. It has no problems handling 3 7950s. There's even Build Videos people have done on YouTube with 3 Way Setups though I don't understand why that would be necessary because Scaling is Never Ideal unless you are playing Tomb Raider. but any who. the REAL reason i believe people probably wouldn't recommend it cause of there is a possibility of a PCI-E bandwidth Limitation. i'm not sure if there is enough PCI-E lanes to handle 3 or 4 way configurations. but it'll definitely handle it fine. if you were to grab a FX 8350 and a Good 990FX motherboard you'd spend about 300 bucks.
I found a combo for a 8350 & Gigabyte 990FXA UD5 for $260.
That was my first idea but then I had everyone saying the 8350 wouldn't cut it.
An 8350 is plenty as it has 38 pcie lines (AFAIK), and should slightly out that of an i5 in multithreaded tasks.
Correction: it will run a single card at x16 and two others at x8 on a 990FX board. That's plenty. Scaling will be terrible with three GPUs though.
you'll be fine. and that combo is very good. and that motherboard has good stability plus you want to give your cards at least a little room to breathe a bit. lol
that to me is an unrealistic budget for core components like MOBO and CPU for three way crossfire ... I would recommend upping your game ...so to say
I would also be inclined to recommend against three way crossfire and if need be sell your GPUs and buy two large GPUs and do a two way build ... because what ever you get will suffer from terrible scaling issues ... especially at the budget confinements you currently have.
How is it an Unrealistic Budget for a Motherboard and CPU?
FX-8350 = $180

990FX motherboard ranges from $100 to $150
the 990FX Fatality from Asrock is $100 bucks right now

$285 bucks right there.
+1 LTT were lying to your face if they were giving off the impression that an 8350 wouldn't be perfectly sufficient.
+1
Well that's what I have and have to work with.
don't sell it to me ... sell it to OP
all I am saying is ... right now you can buy three R9 290 for under $900 ... but I would not recommend doing a three way crossfire ... I would say use one R9 295X2 instead ... much less hassle and better overall performance
sorry I'm a bummer dude ... I do not mean to put you down ... I am old and stuck in my way ... I hope that some of these guys with more experience with multiple GPUs can help you out
EDIT ... plus I've been drinking .. I know no excuse just a day in the life of
Those GPUs are going to be very power hungry also ... so you will also need a very good PSU

I have a Lepa B850.
It supports Multi-Gpu setups.
It has 8 PCI-E Connectors.
LEPA stuff isn't that great and with all those 12V railed I' wondering if it will be up to the task.Plus 850W is gonna be close...
