Could my PSU handle it?

I was thinking of doing a little upgrading on my PC.

What I have now is:
Board-760GM E51 (fx)
CPU-Phenom II X4 @3.0ghz
RAM-1x PNY optima 4gb DDR3@ 1333
GPU-HD 5750 OC'ed

3x2.5"Laptop HDD's
1x3.5 HDD
Multi-Card reader
4x120mm Case fans
1x200mm Case fan

All that is running off an Antec VP-450.

Now what I want to to do is switch motherboards to this:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
or this:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
and then crossfire with another 5750.

Is this doable with my PSU?

And how do you think my performance would be in games like GTA IV or Far cry 3 @ 1080p?

you would see a decent gain in those games with the xfire of a 5750, but you'd see a much higher gain from just purchasing a 7770 or 7790 (just a little over $100) and they support DX11 which will help out in the newer games. As for if the psu would be enough to run 2 5750 in xfire, you'd be cutting it real close, you wouldn't have any head room to do any overclocking and you may not have enough power to run everything you have going there (HD wise)

Agree at 450w you would be cutting it really close. For me I think it would be really to close for comfort.

I would also recommend getting a HD 7790 instead of going Crossfire.

Figures it would be cutting it close.
Guess I could take 2 HDD's off if need be.
I don't think I would really need to overclock my CPU for this configuration.

Also, the 5750 has DX11 support.

This just seemed like a cheaper option than buying a 7790 or 7770 cause i want a new board and a 5750 is around $50 on ebay.
Total would come out to be around the price for the 7790 or 7770.


Is microstuttering really that bad?
Keep hearing how it is bad on AMD cards.
Or is this another NVidia fanboy type thing?

like i said earlier you'd be better off grabbing a 7790 instead of the 5750 in xfire. Then you wouldn't really need to upgrade your motherboard quite yet, and later on you could grab the new mobo and some more ram. But performance wise it would be almost the same i suppose, as for microstuttering, it only happens when frames have a severe drop then the gpus will ramp up to try and compensate giving you the "stutter" It really comes down to what you want to do and like i said before youd be cutting it close with the psu you have.

Option 1: Grab a 7790 (comes with a free game) and wait to upgrade the mobo and ram later or
Option 2: grab that mobo and another 5750 and get almost the same performance and what not.

choice is yours, cheers
edit: as for the nvidia comment, it happens with nvidia also, just more prevelant in older amd cards.

Ok so I just ordered a 5750 off ebay.
I look at the pics harder and turns out that its really a 5770.
Will my PSU still work for this?
I am planning on upgrading that soon but will it work for a little while?

Extreme PSU calculator is saying it will be about 341 watts.
Which is cutting it pretty close.
