MOBO and Graphic compatible help

[John_Sotiriadis]

Can u please help me. I went to your website but i could not fill all format because i cant remember some info. I have the Motherboard Asus Rampage 3 Extreme with a Nvidia GTX470 graphic card. I want to upgrade my machine and get the Nvidia GTX770. But on the site the motherboard it says it is PCIe 2.0 and the graphic card it is PCI Express 3.0. I wanted to make sure if it is going to be compatible, i find forums that it says it is but i want to make sure before purchase it. thank you for your time

Welcome to the ROG forums, John_Sotiriadis.

PCIe 3.0 is backwards compatible with PCIe 2.0. You'll have no problems running a GTX 770 on that motherboard.

and after the summer i was thinking getting 1 more GTX770 and SLI them, would u recommend it or? i mean 2 GTX770 is better than 780 and TITAN and 690 are 2 expensive for me

A GTX 770 SLI configuration is faster than a single GTX 780, Titan or 690.

faster than TITAN? not sure tecnicaly yes u get double performance but mostly SLI told me u get about 3/4 the power of cards or bit more, but not max. Anw again thanks mostly for motherboard will order next week

Here's a nice GeForce GTX 770 SLI review so you can look at the numbers.

If you want to compare stuff like this go over to the Anandtec site and look at the bench section. They have all the recent graphic cards to compare.

Yeah, Anandtech's bench section is great as far as GPUs.

I wouldn't use their CPU bench chart, because they're missing a lot of chips.

ok one last thing i already order 1 gtx770, but after summer will get 2 for SLI. The heat will be problem? or will be at the same lvls of 1 gtx470 ( and those people say do get heat a lot)

If there is adequate clearance space between the GPUs and the airflow in your case is optimal, they will be fine.
