New build advice cpu vs gpu

Hey guys so i am looking into building a new computer for windows 7/dx11 cards. Unfortunately, I will not have the funds to build a new computer. So my question is should i upgrade my cpu to a core i7 920? Or does my processor still have enough juice left to not cause a bottleneck if i go for the new dx11 cards from ati when the come out?

my current system:
e6750 @ 3.2ghz
4gb patriot ram
sapphire 4850x2
750 watt pcpc
gigabyte p35 ds3r

so do you think my e6750 @ 3.2 will bottleneck the 5870x2 when it comes out?

No at 3.2 ghz it won't bottle neck a new GPU. Of course a new cpu will help but that cpu at 3.2ghz should produce good frame rates with any video card.

You can always pickup a single 4850 to go along with the X2. Oh and take a peak into the AM3 builds, you could migrate to a new proc and board and keep your same ram if you wish.

I say to you this. Any Dual core at 4.0Ghz will bottle neck a 4870-4850x2 and up.
Now i would wait for p55 boards. Im planing on either getting a i3-i5, just waiting to see how things play out for them. Basicly im headed for some ddr3, Top air cooling, 32nm proc. I would suggest a Phenom II 940-955 a xtreme hpase asus board, xiggy heatsink, and some 60-40 dollar sticks of DDR3 ram. I would get the 955 to 3.9Ghz . OR wait for sata 3 p55 boards with 32nm rape overclocking chips with ddr3 to . Just get a 5800 something, I probable get there single fastest card setup .

Yea i was defintely looking at the am3 brings for their price/performance but when i look at the tests by tpu and other sites the i7 just seems to wipe the floor with amd's proc's.

The video card will give you better gaming results than the cpu, period.

yea, i'd definitely wait and see what i5 can do, which according to "released" previews that hopefully are somewhat accurate. the i5 will perform very close to that of current i7. I myself just sold my HD 4870 to save for an HD 5870 along with an i5/p55/ddr3 build. gonna take some time but i'm saving till probly oct time and then purchasing.

As for your CPU bottlenecking, i definitely think it would bottleneck an HD 5870x2 as results have already shown that the c2d e8X00 series bottlenecks multi-gpu's so your CPU will definitely bottleneck a next gen multi-gpu. I'd personally save and see what the very soon to be released hardware can do and see comparison to your current performance.

if it produces playable frame rates then it's not bottle necked.

ok let me refrase. Anath, your CPU will keep an HD 5870x2 or any current multi-gpu setup from the maximum potential performance it could provide. lol

I believe a I7920 at 4.0 ghz will produce a few higher frames than a Qx9650 at 4.0ghz with the same video card but is that a bottle neck? If a cpu gives you decent frame rates with any video card it's fine and his cpu is fine for now, a better gpu is way more important, even more so as the resolution gets higher.

Who cares, as long as it still maxes everything at playable framerates? The only thing effected would be benches.

Thats all i care about...cuz right now my card does a pretty good job at all the current games, however i have noticed when i max out the games my card isnt performing as well as it used too. It looks like i will wait to see what the i5 can do and see if i can get both a new i5 cpu, motherboard, ddr3, with the new 5k i want to buy. Thanks a lot guys!

i don't know if i going to confused you but i say x58 with core i7 920 right now will be best chose like news say about i9 seems x58 will be stand up for a long time and you find best performance with x58 with overclocking core i7
or you can switch to AMD , phenom II 955 with good mobo will be cool and i see better than i5 idea
last thing i want to say "if you don't have big jump for score better stay on ground" so you have good system right now and no need to change it

Looks can be deceiving. If your on budget you'll be better of buying a good AM3 mobo, CPU and RAM. Whilest the I7 is a awesome CPU its pricetag is still on the hefty side. Not to mention the 1366 motherboards.

Your system is already great for gaming, 4850 X2 is a great GPU.
