What is the point of the 7790HD?

post #1 of 8
Thread Starter 
I bought the MSI 7790HD because it was new and it has the GCN. However, as the month has progressed, and this being a great card, I have been wondering about upgrade options. See, I have an old Core 2Duo on a Gigabyte P45-UD3R board, and it runs well.. I can feel the tiredness of my system, and I am wondering the best way to bring out the graphic capabilities.
Thinking about it, I have wondered if any of the new and upcoming APUs will have the ability to Dual Graphic with this 7790HD?
Would it work well in a CrossfireX configuration?
Kalveri(sp?) chip looks like it will match with the GCN, but am curious if there would be a benefit.

I will be using this computer for gaming (BF3, MW3, SWTOR, Metro) and general computer use. I am planning on a mITX build because I will be also using this in an rv. Any comments will be greatly appreciated.

What model c2d do you have?

I had an overclocked e6600 that I recently upgraded to an fx-6350. My c2d was a GIGANTIC bottleneck it turned out. My fps in all games increased 20-30 and and I am able to run the graphics at far higher settings with higher frames than before on lower settings.

I have a 5850.

I have the e7400 clocked at 3.0gHz .. I think there is a bottleneck. that is why I am wanting an upgrade path that will work with my 7790HD.

Will it be able to dual graphic with an APU - probably not.

Will it work well in crossfire? Eh, not spectacularly but you probably wouldn't see reduced performance.

If you are noticing problems in BF3 multiplayer in particular, the problem is probably more your old dual-core CPU than the video card. Turning down graphics settings should make the video card perform fine on 1920x1080, but that won't help an inadequate CPU.

Unfortunately there's not a microcenter near you for cheap CPU deals (nearest is in the D.C. area). So if you want a significant CPU upgrade you're pretty much looking at an fx-6350 + mobo ($220 ish) or a haswell CPU + mobo ($250-350ish).

Run 3DMark 11 and post your score. (Performance Preset)
If you have a score lower than P4600, then your CPU definitely should be upgraded.
Fortissimo

Point of HD7790? Performance per watt (78-100ish Watts max) at a performance level adequate for 1080p. smile.gif

The HD7750, GTX 650 and Gtx 650 Ti are more efficient but struggle with 1080p. The HD7850 (~101W max ) is supposed to be more efficient than the HD7790 though if you take into account OCs to 1Ghz at stock volts and 2GB RAM.

It's a shame that it released at a $150 pricepoint though. That combined with the GtX 650 Ti Boost 2GB being better kind of killed it. The sales of Hd7790 for $120 or so are steals though.

2GB HD7790 draws about 87-115W , 128bit memory kills it : http://www.techpowerup.com/reviews/XFX/HD_7790_Black_Edition_OC/24.html

You probably want to upgrade the CPU to a core i3 or AMD FX. Maybe even a Phenom II would work.
