Is this a necessary upgrade for a PC77 sold and purchased in the USA? In a particular US state?

nothing is necessary , but it does make the .177 cal faster and more accurate. i found however the 22 cal, was already a larger port. you can drill the .177 you have out if you have a good way to hold it , i found the steel soft and easily marked in a vise and vise grips but still doable, most that are sold in the US that are rated over 600 ft per second already have a large port in them. then it is the flat top piston and valve modes to get more power.

Find model of your motherboard, go online to manufacturers site and read thru the specifications to learn what type and brands of memory they support. Most of the memory makers also offer compatibility information on their sites. Personally I find that Dell, HP and others make the computers so its impossible to upgrade from what they built. Depending on age of your's and the OS you may be better off with a new tower. XP Support ends in April 2014 so unless your upgraded to Win 7 thats another item to consider..... Good Luck

It depends on other factors: Is this part of an upgrade or just a replacement item? The size of the power supply housing is important; it should be the same equivalent size as the original equipment being replaced. If these considerations have been checked; yes it should work just fine.

It's hard to pinpoint precisely, but considering you have a socket 775 motherboard, I'm guessing the rest of the hardware is a bit dated too. You will get a speed bump, not a major one. If you couple that cpu upgrade with a SSD hard drive, then you will notice the difference.

Not out of the box, but the upgrade key is fairly inexpensive and the process is easy. This isn't a Dell provided custom solution like you'd build from the website, it comes in full retail packaging it's mass produced to this spec.

H.E. look up the specs on your computer and it will tell you what your computer can be upgraded to. Hope this helps

Depends on the os and what you're upgrading to. Check on the os website (ex: Windows) to see if your current version supports your upgrades.

Absolutely. One of the easiest to "Upgrade, by downgrading." All drivers are simple to locate.

Hi Gabriel I'm not sure, I went to www.crucial.com. I downloaded their Crucial System Scanner, it analyse's your system's hardware and provides a list of compatible upgrades that will work best with your system's specs and capabilities. Then I went to amazon because there were slightly cheaper. hope this helps you x

Check the requirements for the OS you want, in this case Win 7. You will probably be Ok. The RAM in these machines are fairly easy to change out and upgrade.

No need to upgrade just for the video card, but I did upgrade the power supply due to attaching a total of 3 harddrives and 2 DVD read/writers and max memory.

Mr. Turner has the right of it. I haven't looked inside the case, but possible problems are not enough space for the new card, and not enough watts from the power supply. Then there is the hassle of upgrading the software drivers. It's not a good idea. It sounds like you want a customized unit. You can go through Dell or find a company that builds to order, or assemble it yourself. Be sure to check out any company that offers customized units. Often the cheapest is not a good idea.

My suggestion is do a search on your make and model on both the H-P website and Tom's Hardware (http://www.tomshardware.com/). I invariably find what I need to know on Tom's site or the manufacturer's. I'm assuming you either have the machine's manual or have downloaded it in PDF format. It should definitely tell you all about your memory and upgrading the same. Hope this helps...

I am not sure but check the specs again or contact ASUS. But you might be SOL and have to upgrade your OS you can get Win 7 for about 89.00. Good Luck
