Building New PC - Need advice on graphics card options (dual 7870 2GB or 770 4GB)

Hello, everyone!

I'm thinking of building a new PC with games like Watch Dogs now coming out with some rather demanding specs.

I won't list out my whole rig specs, but it will have an i7 4770, 16GB RAM, and I need advice on the graphics card...

I bought a 7870 2GB late last year to hold me over til I could build a new PC. So, here's my question...

Do you think I should:
A.) Just put my existing 7870 2GB card in the new PC for another 6 months or so and buy a $450 card then?
B.) Buy a 2nd 7870 2GB card and run them both in the new PC?
C.) Buy a GTX 770 4GB card for the new PC to take advantage of Nvidia-specific features in games like Watch Dogs?
D.) Have another suggestion...?


Follow-up...will a Corsair 750 watt power supply run two cards (two 7870 cards or two 770 cards)?

The advantage to C is that I can keep the 7870 in my current PC. Otherwise, I may have to buy another cheap card to put in it for it to be worth anything. It has an i5 750 in it overclocked to 3.8GHZ, so it is still worth something...

THANK YOU!!!

well, vram does not add when in crossfire/sli, so 2 2gb cards will still only be 2gb vram. i would suggest a single card, and to match your cpu and ram, a gtx 770 or 280X or higher card will do, and if you only use 1 monitor at 1440p or lower, 2gb vram is enough, if multiple monitors then get 3gb or 4gb.

That is really good info... So, I only use one monitor, 1920 x 1200, or sometimes run a HDMI cable to my 1080P TV. Therefore, are you saying that getting a 3GB or 4GB card is a waste? Would that extra VRAM help with anything (now or in the future)?

I ask that last question, because I thought I read that more VRAM helped when heavily modding games like Skyrim.

Thanks!

vram does help with heavily modded games, so 3gb vram should be fine. how much money do you have for the graphics card?

I really don't want to spend more than $450. I'd rather buy another card in a couple years than spend more than that, now, since I don't feel I'd be getting the "best bang for my buck" after that much.

16GB of ram is over kill, get 8 gb of ram and with the money you save get a nice GTX 780.

So, you think this card would be a better investment than this card?

And, I'm guessing, by the R9 290 suggestion, you don't really think the Nvidia-specific features are really worth only considering a Nvidia card...? :)

i would keep the 16gb ram, watchdogs will be pushing 8gb... and yes, taht 780 is a better investment than the 770.
