Hello good people of tom'shardware,

I am planning to upgrade my pc by adding the MSI GTX 970 onto a GA-78LMT-S2 motherboard with a AMD FX 6100 3.3 GHz processors.

Here are my current specs:
http://www.newegg.com/Product/Product.aspx?Item=N82E16883258020

I have a couple questions:

1.) Will the card fit in the slot on the motherboard (are the MB and GPU compactible?) I have read that PCI 3.0 card is compactable with PCI 2.0 slot.

2.) Should I expect a lot of bottle neck, given that my processor is not the best?

3.) Is the 450W power supply sufficient to run the AMD FX 6100 and GTX 970?

4.) Is there anything else I am overlooking or should be concerned about?

Note: eventually I plan to switch out the motherboard and upgrade the processor to i5-4690K, and run two GTX 970, what would be a good motherboard for a decent price to run both cards in SLI?

Thanks in advance for all your knowledge which you share.

The Card will both fit, and run within 98% of it's capability in a PCIe 2.0 16x slot.

You will have a bit of a bottleneck, moreso in games that are CPU heavy such as Battlefield. However, A bottleneck doesn't really mean much if you're pushing 80+fps still. ---Card will be bottlenecked, but it shouldn't matter much.

3. 450w will be enough, my 2x SLI 970's pull 450w when gaming, so you will be sliding in under that. Assuming the 450w is of half-decent quality.

4. Just make sure you find your PSU brand, if it's a lower end brand I would advise against adding a GTX 970, if it's half-decent you will be fine.

Personally I don't see motherboards as being too different from eachother unless you are a REAL enthusiast. I just picked a Brand I was familiar with (Gigabyte in this case) And made sure there was decent spacing in the slots for dual cards.

1 - The motherboard is not an issue
2 - Bottleneck , not much depends on games
3 - A decent 550w is better choice

You won't lose performance in a 2.0 slot.

Thanks a lot both of you ( azathoth and SR-71 Blackbird ). I think for now I will get just the GPU and later I shall upgrade all PSU, MB, and processor. Once again, thank you very much!

PS: My current PSU is Cooler Master RS-460-PSAR-I3, hopefully it the PSU will last with the card at least month or two before I purchase new one.
