R9 280X vs. GTX 770 (2GB)

Yay! I actually finished doing the tests that I said I would do in this post. Whenever I sit down to make a post, I always don't want to type a whole lot, because then I have to get up and walk it off for a while and I give myself a headache. But whatever, I will now start typing this post. >_>


The Cards are on the Table

Puns! But in this case they really are on the table. In any case, I (as I often do) made some adjustments to my test. I didn't test the R9 290X because I wanted to get the 770 and 280X tested and written up first. But I successfully modded my R9 290X with a Kraken G12 and Asetek 570LC AIO cooler, and managed to overclock it to 1200 MHz which is a nice result. I might make a post on that later.


Anyway... I love graphics cards so let's take a look at the cards.


Sapphire Radeon R9 280X Vapor-X

The card on the left is a Sapphire R9 280X Vapor-X. This card launched for about $350-360 making it actually quite expensive for a 280X, but it is a great model. It's still cheaper than the $400 GTX 770, although the price of these did come down. Some basic Tech Specs! Yay!


For those that don't know, the R9 280X is a re-branded HD 7970 GHz Edition which is a Re-branded HD 7970, with higher core clock speeds and faster GDDR5 memory.

I enjoyed typing that. Anyway, for the GeForce


MSI GeForce GTX 770 Twin Frozr

The card in the middle of the top picture is MSI's Twin Frozr GTX 770. It's a nice cooler but it doesn't come with a back plate which doesn't even make me a Sad Panda because I don't really care. Anyway this card was originally launched for $400, but I think it got a price cut.


For those that don't know, the GTX 770 is a re-branded GTX 680 with faster GDDR5 and a slight increase in core clock speeds.
