HD 7970 & Ivy Bridge?

[dogboy]

I just have a quick question will waiting for the new Ivy bridge processors make a significant difference when using a HD 7970. I read someting about PCI 3 slots cant be used as efficiently with Sandy Bridge? BTW I am not computer savy and thanks for any info I am new to the forums.

Lga 1155 SB cannot use pcie 3, you will need lga 2011 or IB lga 1155. Pcie 3 is pcie 3, regardless of platform, but the card itself just doesn't utilize that much bandwidth to be affected by the switch to 3.0 (for at least these resolutions). But with IB coming out in april or so, it might be worth a little boost in cpu power since it'll cost the same as the cpus they replace.

I believe with Ivy bridge and a 7970 and other misc parts your should be set. Even tho Nvidia renders better with intel from what i have been told

Gpu and cpu company does not matter. You can mix them and get the same performance as long as it's not bottlenecked.

This what I dont get. The PCI-E controller is on the cpu. Other side the gpu. Now what does the mobo do with controlling the packets?

Anyways I think he asked with the number of slots the card takes. Ivy bridge you will be fine with the card just don't go buy a 450+ card when using a below 1080p monitor.
What PSu do you have btw

I am buying a Rosewill CAPSTONE Series CAPSTONE-650 650W Continuous @ 50°C, 80 PLUS GOLD Certified, Single +12V Rail, ATX12V v2.31 / EPS12V v2.92, SLI Ready, CrossFire Ready, Active - PFC Power Supply. I believe I did not make my question clear. I simply wanted to know whether I should just go ahead and buy my computer components now or will waiting until IB comes out in May make a significant difference in gaming. From what I understand if I connect the HD7970 to the PCI 3.0 slot the current SB cpu's treat the slot as if it were a PCI 2.0 slot. Thanks for the response

OK, by the looks of the article and what you said I guess waiting for IB really is not worth the wait for gaming purposes. Waiting for IB is only worth it if I'm looking for a tad bit more CPU power and energy efficiency. Thanks for the reply
