GTX 765 in an R2?

'lo,

Did some searching but did not have any luck finding threads on putting a GTX 765 in an R2. Anyone know if it has been done?

This R2 shipped back on 11.22.10 and the GTX 285 SLi are getting tired. Looking on eBay I see 765s are fetching a bit over $300 which seems like an excellent upgrade. Dropped a 920XM in a awhile back and now debating if dropping the coin for a new GPU(if possible) would be the hassle or just put it towards a new rig.


Thanks!

 

an even more excellent option in the r2 is to use 7970m's or 8970m's. See sig. Otherwise as far as I know, the last SLI that works on the R2 is the 580m.

 

User @champeto on TI Forums got 765M working in R2 just fine, but like Sangemaru said, 8970m or 7970M would be a better choice price/performance wise.

 

I believe the same, the 7970m would be a better option. We won't be able to support the setup if the system is in warranty because it's not officially supported but we have seen success stories on this setup.

 

680M or 770M are options too.

 

No desire to go down the SLi road again just want to bring the graphics back from the dead. Checking eBay I see a 7970s up in the $450-500 range and not sure the performance increase over a 765 is worth 50% more. Unless the 7970 is that much stronger than a 765 I would rather put the savings from going with a 765 towards an SSD. Will have to ponder the choices a bit more.

Actually, a single 765m is barely an upgrade at all, compared to 285M's in SLI. So little, that different driver configs alone would put either one out ahead in performance. Now a 780m, thats a completely different story. You'd be around 2x the benchmarks and performance, and using less power and less heat.

 

If you don't want to pay $450-$500 for a 7970M, why not try the NBR marketplace. Not too long ago 2 7970M's were sold for $330 shipped on the NBR Marketplace: http://forum.notebookreview.com/computer-components/736040-sold-7970m-x-2-x-bracket.html

Just post in the Want to Buy section and wait to see if someone will sell you a card. The 765M really isnt much of an upgrade at all... especially with next-gen here games will start to become a lot more demanding. It is best to get the performance needed now so you dont have to worry about upgrading anytime soon down the line.
