Best AM3+ Mobo for $80-120?

Hi there! I'm looking to build myself a new system, I just really need to know what is the best AM3+ Mobo for around $80-$120 range? Give or take a few dollars. I mainly want it for gaming and future proof, this is my current processor and the one I will continue using for the time being.

AMD Sempron 140 Sargas 2.7GHz Socket AM3 45W Single-Core Processor SDX140HBGQBOX

This is the Ram I'm going to buy with it.

G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL

This is the current PSU I have and the one I will continue to use until I get some extra $$.

Coolmax V-500 Series 500W 120mm ATX Power Supply

I also have a PATA HDD and DVD-ROM I would like to continue using, so if anyone knows of a IDE-Sata connecter please post it here.

I also had this graphics card picked out http://www.buy.com/prod/xfx-hd567xznf3-ati-radeon-hd-56...

What do you think? About the motherboard, I would like to have 2-3 PCI-E x16 slots that can run at 16/16 or atleast 8/8 for crossfiring later on.

I currently only have a crappy CRT monitor that only goes up to 1280 X 1024 yes I know, I need a new monitor, and I'm going to get one soon.

The upgrades I'm getting within a few months are

New monitor.
Quad core processor.
New HDD.
New Blue-Ray drive.
Better case.
750 W PSU, a brand name.


What do you think? The parts I have listed now such as processor and HDD/DVD/PSU won't be staying very long, 3-5 months tops.

Thanks for looking.  

Regards,
Eddie.
