Hello,

I have upgraded my rig from amd phenom 2 to intel i7 4770k and a new mobo. MSI Z87 G43 and i could not afford to buy GD65 or higher top spec Z87. From what i have seen my mobo specifications, i have PCI-E 3.0 and PCI-E 2.0. I am looking to upgrade my 9800gtx+ for dual ATI R9 280x or Geforce 780TI or GTX. I have researched the fourms for crossfire based on that lanes, if i have dual ati graphics card and both will be bottlenecked by PCI-E 2.0 against pci-e 3.0 like (x4,x4) I am worried about putting crossfire setup on it. Any clarifications and suggestions please.

Thanks
 
If you can afford a 780 Ti then I would just get the EVGA GTX 780 Ti w/ ACX and not worry about crossfire or SLI at all right now.

If you want to in the future then do it then but the 780Ti will max out anything you throw at it.

yes i can afford it. but can you explain about the crossfire with the pci-e problem?

theres nvidia maxwell coming out. should i wait or? even the new broadwell cpu >.<
 
and i have 650 corsair gx powersupply. any recommendations to upgrade it prior to newer graphics card?

If you are going with a single card, then your PSU is more than enough to run any of today's single cards.

You can run dual 7950s in crossfire with that PSU as it is the same setup as I am running on my rig.
 
You can afford $700+ in gpu, but can't spend and extra $50 to get a better mobo? Yes, pci-e 2.0 x4 will affect performance in cfx. Either get a better board, or stay single gpu.
 
well, i bought the upgrades within the first budget. now i have received a second budget which is larger so i am looking to drop in a new gfx and a new monitor perhaps.

so are u saying that my motherboard is worthless for crossfire cause the pci-e 2.0 will destroy the pci-e 3.0?

Thanks

Get the best single card you can afford. Crossfire and SLI do NOT scale the same in every game.
 
Don't know about CFX but SLi scales very well in almost 90% of the games I play and I play a shit ton of games. There are some really stupid comments about preference of a single card system over SLi. If you want to go SLi then you need at least PCI e 2.0 with X8 lanes on both cards. If you can get PCI e 3.0 and X16 lanes on both cards (will be a very expensive board around 250+ dollars) then that is the best setup.

I wouldn't get a GTX 780 Ti if you are planning to change the board and PSU. Recommendation of PSU is a 1000 watts (see my sig for a great and cheap corsair psu) and two GTX 780s in SLi will eat games for breakfast especially at 1080P. If you want to go higher even then a GTX 780 SLi setup is sufficient.

Its a age old debate. Some games do not even support multiple cards. To each his own, but after going down both the CF and SLI route with high end cards more than a few times, I personally prefer a single card.

Don't know when was the last time you tried CFX or SLi but you should SLi that GTX 780 and see the kindof performance gains you get. It is unmatched and totally stable without lag/microstutter bullshit of the old GTX 500 series days. I have used 3 setups in SLi now and I don't think I can go back to single card even if it is the GTX 780 Ti (which btw I can already match in terms of stock clocks with my OC GTX 780). A single GTX 780 is just not sufficient for 144 Hz gaming.
