I have been out of the pc hardware loop for a while and was wondering if upgrading from a Nvidia GTX550 TI to a 770 series card would be beneficial. Or are there other considerations. My budget is around $400 Canadian.
i did a similar upgrade that you plan on doing. i had the GTX560ti and upgraded to the GTX760 and i was not disapointed(60FPS in BF4, Ultra settings 1650x1080). so you should be similarly or more pleased than i was with the 770
For 1440p I would strongly urge you to make sure you get 4GB vram card. I settled on 2GB 670 when I got my 1440p and already finding myself having to scale things back in some titles.
I would like to report back that i have upgraded and what a difference . ended up with the following. E-VGA Geforce GTX 760 SC 4GB it was around $329 CDN which i thought was a great price considering it's a 4GB card. thanks for the help everyone.
