Question about graphic card & about directx

Closest was the quad core i7-950 at 188 (pounds) compared to the 2500K at 166.

Cheapest 6-core was i7-970 at 440 pounds.

And the i7-8xx's start at 206, and are considered inferior to the SBs.

Basically to get any better performance than Sandy Bridge you need to spend a huge amount more. And even then it may not be worth it if you don't run highly threaded applications.

Wrong, the older gen i7 quads perform better overall substantially per $ than the newer sandybridge i5s - this is due to the fact that they both can OC to the same level, while i5 has faster architecture because of the shrink, the i7 will "Always" beat it on anything heavily threaded, and often beat it on 4 threaded apps because the i7 uses the extra threads to run the os etc, while the i5 cannot do that (no hyperthreading).

Thanks to avoid dispersion, I ask a simple question, it has not yet been answered to.

Get the best video card you can afford! Unless you are using a directx9 card you are not missing out on any graphical features until they add DX11 support.

Really don't want to keep this going, (OP still hasn't got an answer and it's a question I'm interested in myself) but It is just incorrect that:

'the older gen i7 quads perform better overall substantially per $ than the newer sandybridge i5s'

recent tests in MANY magazines and websites demonstrate that the i5-2500K outperformed all but the most expensive i7s in everything but highly multi-threaded apps.

My last post showed that the extra performance also comes at a cheaper (MUCH cheaper for comparable performance) price than the i7s too.

The ONLY proviso in all this is whether or not you intend to run heavily multi-threaded apps. In this case, as you say, the top-end i7s will be better, but even then many people would be put off by the extra expense.

---------------------

Now - can someone answer this?:

gtx560ti 2GB OR gtx570 1280MB ???

for CoD obviously, , at 1680x1050 or 1920x1080 and for high settings.

You might have to wait for them to get everything ironed out, but I would probably go for the 2GB version. It's going to pay off if you are gaming at the higher of the two resolutions and want to up the details.

As for the OP's question, like pretty much every hardware question, get the best you can afford unless it's one of the specialty cards that only gives you a 5% FPS boots more than another card $300 cheaper.

"many magazines" doesnt really count as a source...
That being said you havent read the post - the i7 can be clocked to more or less the same OC clock as the i5 can, they are both the same price (930/920 cheaper and 940/950 slightly more) but they have double the threads. Now its getting really tiresome, but do you seriously think the thread count of apps wont be increasing rapidly from now on? New phones coming out are dual core, the new ipad 5 is probably a dual too. BFBC2 runs 8 threads. Now even if you only run 4 threads, so even with the i5 - the clock is the same, the i5 SB wins slightly interms of speed because of the new mem/arch BUT the i7 can run the OS and other apps using the spare threads and comes out even or on top. In addition this gap will only increase into the future.
I5 SB will always lose to a i7 N unless its a K version SB then you can OC it, then its even until you get to newer software and the I7 wins. Its the better longterm buy.

Your capacity to discount evidence that doesn't fit your desired conclusion is impressive. This being an Internet forum and not an academic journal it seems a little OTT to supply detailed references.

You're still maintaining that the i7s are cheaper. At the suppliers I usually buy from they aren't:

The 930 is 229.99 at OCUK (and currently out of stock with no ETA) against 179.99 for the i5-2500K.

Regarding number of threads - with SBs you have a choice of 4 core hyper-threading with the 2600K - equivalent to the lower i7s. There is possibility that 6-core SBs will be coming out for the 1155 socket.

Even if that doesn't happen, I could replace my motherboard AND get a new 6-core cpu for less than I would have to pay to get the cheapest 6-core i7 currently.

Sorry I dont speak for UK prices - only US online and retail that I have seen, so I my comment cannot (and does not) apply to the UK if what you say is true interms of a big price gap. That being said NO i5 has hyper threading!: http://ark.intel.com/ProductCollecti...familyId=42912

Hyper threading is only for i7s. Also a 6 core SB cpu would be great, but that would be replacing the current i7 980x gulftown cpu as their top cpu and will probably for SB take on the same price ($1000). On the other hand once we reach Ivy Bridge architecture (28nm from 34nm) then its likely we will see midrange 6 cores and high range 8+ cores for the upper end. I am holding out hope they stretch the 1366 alittle more and give us a 8 core gulftown as or after the 995x in 2011/2012.

In any case what you have said about the 6 cores validates my whole point - that for the future you need more cores/threads. While the i5 SB is newer, it loses out to the older and (in the US) comparably priced i7 which can match it closely in thread limited performance but spanks it when you go to heavily threaded apps = the future. So $ per performance the i7 N is better atm imo.
