Which gfx to choose?

[Niklas Hervig]

Hello, I cant decide which gfx to choose.
I've looked at following:
ASUS GTX750TI-PH-2GD5
ASUS GTX750TI-OC-2GD5 (Price difference) GIGABYTE GeForce GTX 750 Ti OC - 2GB
ASUS GeForce GTX 750 Ti Strix - 2GB
GIGABYTE GeForce GTX 750 Ti OC WF - 2GB
ASUs GeForce GTX 750 OC - 2GB GDDR5
MSI GeForce GTX 750 Ti Gaming - 2GB
GeForce GTX 660 OC - 2GB GDDR5
GIGABYTE GeForce GTX 650 - 4GB GDDR5
ASUS Radeon R7 260X OC DC2 - 2GB GDDR5
ASUS Radeon R9 270 OC - 2GB GDDR5

Anyone know the differences on the gtx 750 cards? the ti oc, ti strix, ti oc wf and etc?

Spec
Gigabyte GA-x58A-UD3R (usb3.0)
Intel i7-950 4x3,06 GHz
Kingston blu 2gb Hyperx ddr3 1600(upgrading them to Kingston hyperx gen 3x4 gb ddr3)
1tb seagate sata 2 7200 rpm
Psu Inter-Tech 700w
And theres not gonna be a problem with pci-e 3.0 and this motherboard?

r9 270 for sure its the best among all the cards in performance also i would advice to get a pair of 2x4 gb ram and get a decent quality 500 watt PSU.

I already got trichannel ram 6gb upgrading them to 12 1600.
My 700w isnt fine enough?

Wattage wise more than enough but quality wise not so much but its totally up to you.

Didnt understand a single thing of that u wrote mate again plz?

700 watt is more than enough for your system a 500 watt is what you need but it should be good quality one like seasonic , xfx etc with 80+ certification i hope its clear now.

Allright thank you.
It was just a standard one. I didnt have in mind to change that. I believe its something that can wait?
Its just more expensive to run the pc with that voltage right?

well as you have a 700 watt psu i think you should have no problem because the PSU will be at 50 - 60 % stress .
