Case upgrade advice needed

Well first thing you need to do is define a rough budget. Also right away you need to realize that the AMD rig will be a lower cost rig that runs right in between a top i5 and a lower i7 rig. I doubt you are considering the top end Intel chip as that's a grand right there. I would say the AMD FX 8 core or a i5 Intel 3rd gen, will rock your world. Ironically I see the FX architecture lasting longer then the next gen Intel. Meaning that your top flight AMD mobo will last for a generation or two with AMD upgrades where Intel is set to un-leash Haswell which it's unclear if it will work with current Intel mobo's.

Thank's for the quick reply.
In the last 2 days or so I read a little about the Haswell CPU.

Doe's the ASRock 990FX MB have enough expansion slots for anything I might want to add in the future ?
Is this model the best fit for the FX-8350 CPU ? Are there any other MB's which would be compatible ?

It's a great mobo for the AMD and as a off-spring from ASUS can be compared to this ASUS and other offerings.

Asus Sabetooth 990Fx/Gen3 AMD 990FX/SB950 Motherboard - ATX, Socket AM3+, AMD 990FX/SB950, DDR3 1866 MHz, SATA III (6Gb/s), RAID, 8-CH Audio, Gigabit LAN, USB 3.0, PCIe 3.0 (Sabetooth 990Fx/Gen3) at TigerDirect.com

Here's another killer mobo from AS Rock:

What is the difference between this one which states it is unlocked:
AMD FD8350FRHKBOX FX-8350 Eight-Core 4GHz AM3+ Processor - AM3+, Eight-Core, 4GHz, 16MB, 125W, Unlocked at TigerDirect.com

this one which states it is Black:

and this one which states it is Turbo:
AMD FX-8350 Vishera 4.0GHz (4.2GHz Turbo) Socket AM3+ 125W Eight-Core Desktop Processor FD8350FRHKBOX - Newegg.com

Ok, what about the Turbo ?

The one from newegg is the only one which states it in the spec's.

Thank's for your replies.

So you are saying they are all equal, even though the spec's are not the same ?
