My pc is 2 years old almost and i only installed win7 about 12 months ago, When i bought my e8400 i did alot of reserch and found that the q8400 wasnt as good as the e8400 for gaming, i was also thinking like you said and to get a new q9550 or the 9450 and a gtx 460. As my psu got enough adaptors for the gtx460? is it just the same 6/8 pin like my gtx260 as?
also i can only seem to oc my cpu to 362 mhz @ 3.258mhz and any higher just freezers up my pc. Im using the nvidia control panel program to oc so it might be that why it wont go higher?
Yes, your PSU should be able to handle the 460. Power connectors have been pretty much standardized, so any 6-pin or 6+2 pin plug on the power supply will fit the 6-pin connectors on the 460. Nothing to worry about there.
I think you're exactly right about the overclocking. Software-only overclocking is generally not very good and can only take you so far; you're much better off doing it in the BIOS, though that takes a little more research. Mainly, I think the issue it sounds like you're running into is that you can do a small overclock without needing to mess with the CPU voltage, but to do a serious overclock, you need to increase the voltage, and the software fails at that, so you hit a certain point and stop. You can overclock the E8400 to 3.6 GHz pretty decently, and if you push it you can get it to 4GHz. If you really want to do that, I would do some research on it first, both about BIOS settings and CPU cooling, since that will come into play with any serious overclocking.
You have stock cooling for your CPU? Are your BIOS locked? BIOS overclocking is much more stable usually.
To be honest I would not go with a Q9xxx chip right now. They are too overpriced. LGA775 is pretty much dead and while still fast you have the even newer LGA1156 being replaced by Sandy Bridge soon...........how far do you want to get behind? Save your money for an i5 750 system or an Athlon II x4 955/965 box.
I agree with you and disagree with you at the same time. Q9xxx does cost too much -- but then again, what Intel CPU doesn't? The i5 and i7 are overpriced too for what they do. Pretty much any machine I build these days is AMD for that reason.
However, the high-end LGA775 processors like the q9550 are still among the better CPUs out there. Even though they're "dead technology," they still beat the hell out of most of the i5s and AMD quad-cores that people are always recommending for gaming. They're called "dead technology" only because you can't upgrade past the 9xxx, not because their performance is bad. A system with a 9550 will probably be good for another 3 years -- most systems not specifically marketed as "gaming systems" are still dual-cores, for chrissakes.
I definitely wouldn't build a new system with a q9xxx (or any LGA775 processor, for that matter), but if LGA775 is what you've got already, I still think that if you drop in one of the top LGA775 quad-cores, that's the best you can do for the money as long as you hang on to the system for 2-3 years. Yeah, 1156/1366/Sandy Bridge/AM3/Bulldozer/Whatever may be better if you're going for benchmark supremacy, but you're paying for a new motherboard too, so add that into the cost you figure for the CPU. The best LGA775 systems are going to remain viable as good gaming machines for a while, so if money is a concern, the upgrade is the way I'd go.
