Yeah, that "sounds" nice and all, but the reality is...
1. The price/performance of going from what he has now to that would be terrible, given he's asking about better PC performance and not relaying that he has the money/will for a new system and a dissatisfaction with his new system. If that were true, then, yes, a new overhaul would be a good idea, but people need to stop assuming this is always the case around here. His system is still good, and I don't see the thread being made because he's dissatisfied with it. He's just looking for more performance in PCSX2, so he needs a little more CPU power. It's better from a price/performance perspective to just drop in a better CPU and/or get a better motherboard to let him overclock versus overhauling the entire whole thing with points that, while true by themselves, don't matter a single bit.
2. There would be
no point going with a Q-anything over a good E8x00 now. In fact, the gains that'd bring if he wasn't going to overclock wouldn't be worth it over his current CPU as it stands. The
only reason for getting more than two cores is if...
A. He has specific needs for one (yep, they're still useless versus more speed in 99% of things), which he has not stated, or...
B. you simply get the extra two cores from moving onto an upcoming standard (Core i7, Phenom II) that already has them by default for most models.
Really, I sometimes wonder if people around here know how to read into the specific situations when these sorts of questions come up, or if they just go "hardware dying, not best there is, not enough cores, etc., so avoid doing" type of responses. To suggest not going with Core 2 because "it's a dying platform" (moot since he's already on it), and then to suggest wasting money on a Q9550 versus a Core 2 Duo really has me scratching me head. I see him saying this...
I mean If I'm only going to gain a few more frames in Ps2 or Dolphin games then it's not worth the upgrade.
...and yes, while a new PC
will perform better, for the price he'd have to pay to overhaul most, or maybe all, of the whole PC compared to the increase in PCSX2 and Dolphin, it'd be a waste of a money. That's ultimately the bottom line here, and it's one that people often don't seem to get, and I'm not about to suggest him to waste his money after he just said that. Had he came in saying he wanted a new system, was dissatisfied with his current one, and/or was willing to pay for one, then it might be different...
