System Upgrade: Difference?

post #1 of 9
Thread Starter 
My wife's system finally needs an upgrade, so I wanted to get some feedback on what the difference would be in gaming performance (only thing she uses her system for) going from:

ASUS Rampage II, E8600 (stock @ 3.33), 4GB RAM, GTX 580

-to-

MSI P67A-GD65, i5 2500K (stock @ 3.3), 6GB RAM, GTX 580

Have followed some info on SB, and I'm assuming there would be a huge difference in performance between the two systems.

Don't want to stick with the 9xx series, because even though the i7 950 is on sale right now, it's still more expensive, as are 1366 mobos, and it seems the 2500K even at stock would be roughly akin to my i7 920 (stock), plus another 2GB RAM for her, and hopefully avoiding any slight bottleneck the E8600 would also cause with the GTX 580.

Input/feedback would be appreciated.

P.S.
I'm just looking at stock comparisons between systems, not OC'ing at the moment.

P.S.S
She plays what I do... games such as Borderlands (she gets no lag right now), Crysis, Guild Wars (very light game), but will be getting into things such as Bulletstorm, Crysis 2, Guild Wars 2, Diablo III, Rage (which would crush her system) etc. etc. Her system runs great now, but tech is being pushed, so I think her system is a bit long in the tooth, at the moment.

If there is no overclocking plan, then 100% get the SB 2500K. Turbo is on by default and will overclock automatically for your wife.

Just in general, the 2500K will perform better across the board than a 950 on all CPU benches. However this will be for gaming so a GTX580 will render the CPU comparison even. The only advantage once again is the turbo on the 2500K. The increase turbo CPU speed will give some minor increase in games.

Thanks for the response.

Not sure what you mean, "a GTX 580 wil render the CPU comparison even". Wouldn't the E8600 dual-core bottleneck the GPU at this point?

Also, if the 2500K would perform better across the board than a 950 (I didn't think it would be hit those levels), and a 950 would crush an E8600 (which it would), plus an extra 2GB RAM, then we should be able to expect a massive difference in performance in general, no?

Yep, expect a good almost doubling in performance across the board from the CPU you've currently got, and if I remember the E8600 correctly, you'd be hitting about the same target (gamer/midlevel enthusiast) as the E8600. As for the RAM, well you really DON'T need the additional 2 GB of RAM (actually...how are you getting the additional 2 GB of RAM to get to 6? SB is dual channel)

If you run benchmarks then yes you would see a massive difference. Actual game play however you would not 'see' a massive difference.

You could try instead upgrading her CPU to a fast quad for cheap instead of a full architecture change.
My system in specs runs all my games at very good performance levels at Max/Enthusiast levels.

4 Gigs of ram are usually enough to run any game fully from memory. Anymore than 4 would not increase performance for gaming.

What do you mean "SB is dual channel"? You can only run 2, 4 or 8GB RAM using SB? Not 6GB?

Good points, but the only problem is that her mobo, Rampage Formula II X48 (775), doesn't support quad cores, as far as I remember (used to be my old system), so I'd have to snag a new mobo w/ a quad anyway.

Wait... thought I remembered it didn't, but just looked it up again, and says it does? Maybe with a BIOS update?

So, not sure which direction to take at this point.

If it is the x48 board? Then yes it does, check a BIOS update. I'm having trouble locating it on Asus website, I can only find the Maximus ii board (P45 LGA775) but this also supports quads.

Google searches shows the rampage formula does support quads.

As to direction I would try for a fast quad for cheap to feed the GTX580, a Q9650 would work fine. Use the other few hundred dollars saved and go to vegas for holiday.

1155 only has 4 Mem slots so = dual channel (standard 4gig 2x2)
1366 has 6 Mem slots so = triple channel (standard 6gig 2x3)

You can run 6 gigs of ram fine, it will just run in dual channel is all.

You could get 6 gigs by running a pair of 2gb sticks and a pair of 1gb sticks, but she's gaming, you'll probably want to go with either a single pair of 2 or 4gb sticks ..
4gb of ram is still more than is utilized in any game.
I just made the same upgrade from a mildly overclocked E8500 @ 3.8ghz to a mild/auto overclocked i5 2500k @ 4.2-4.3ghz
I don't know of any games that need/use hyper-threading, so save some money and get the i5. Even if you don't plan on overclocking her system, the k version combined with most good motherboards will automatically overclock to at least 4.2-4.3ghz and it only costs ~$10 more than the locked version.
The performance gains are amazing, I was at 100% utilization on both cores in almost every game, even World of Warcraft was harshly choking on the cpu (it's limited to 3-cores max), now under the same conditions & ultra settings I'm not even getting close to max utilization on the used cores. The 4th core means I can play mp3's in the background or whatever else I want to do without impacting performance.
I loved the stability of my Core 2 Duo system, but it really was cpu limited in almost all modern games.

That was my original plan, but the 775 quad's are more expensive now than they were when they were released and they lack a lot of efficiency refinements, not to mention raw speed. A Q9650 @ 3.0ghz is ~$340 while the 2500k @ 3.7ghz (bone stock turbo, most boards will set above 4ghz) is only ~$225.
