Product description
Intel® 64 Architecture
Intel® 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software.¹ Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.
Enhanced Intel SpeedStep® Technology
Enhanced Intel SpeedStep® Technology is an advanced means of enabling very high performance while also meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep Technology switches both voltage and frequency in tandem between high and low levels in response to processor load.
Execute Disable Bit
Execute Disable Bit is a hardware-based security feature that can reduce exposure to viruses and malicious-code attacks and prevent harmful software from executing and propagating on the server or network. Help protect your customers' business assets and reduce the need for costly virus-related repairs by building systems with built-in Intel Execute Disable Bit.

The Socket 775 technology (i.e. the motherboard that accommodates all Core 2 Duo/Quad processors) will in the not too distant future become an out of date line. The i3/i5/i7 Intel processors all require either socket 1156 or 1366 motherboards and DDR3 RAM, so if you wanted to buy one of these new-line CPUs, you are in reality buying a new motherboard and RAM too. The costs add up quickly in this case: A modest i5 CPU/motherboard/RAM trio would be

which, after p&p, will set you back the better part of £300. If you are prepared to commit that sort of money to upgrading your computer, then go for it, because it will be money well spent. However, However, if you want to retain older components (motherboard, RAM) and give your computer a boost, this is absolutely the CPU for you.
I bought one of these CPUs to upgrade my brother's E6300 1.86GHz (the very first Core 2 Duo). In Windows 7's Index, this CPU scores 7.2. Obviously this isn't the most rigorous benchmark, but it does give a broad indication of a CPU's power, and to put this in context, my Q9550 scores 7.3, but at current prices is more than twice as expensive.
There is only one draw-back with this CPU - it requires a motherboard capable of 1333MHz FSB. If you're upgrading from an older Core 2 Duo, it is not a given that your existing motherboard will automatically support the Q8300. If it turns out your motherboard only runs at 1066MHz, then try finding the Q6600 for a reasonable price. It's another great CPU, and if you hunt around a bit you should be able to find it for around £160.
In terms of overclocking, I have never really bothered, so I'm not in a position to say anything about this here. There are plenty of references on the net about this, so you may want to look it up if that's your thing. A stock, though, it's strong anyway.
I'll also add that Intel seemed to have improved the standard heatsink that comes with the processor - I had no problems fitting it, and according to the BIOS, the CPU idles at a comfortable 30 degrees.
All in all, a brilliant buy for a cost-effective upgrade.
Eventually Intel suggested a possible reason. The 'graphics threading' of the Quad core processor was clashing with the Ati Drivers. Solution, go back to earlier drivers!. However I'd had enough by then. I put my Dual Core E7500 processor back in to my system and lo and behold a wonderful stable computer again with unlimited game play and NO Blue Screens! I threw the Q8300 in the bin and accepted that was £100 (plus all the extras) down the drain.
So just be careful if you are upgrading to this chip. May just have been my combo but maybe there is a real problem here.
