I need help upgrading my 10-year old Gateway DX4822-01

I recall Newegg used to have a tool to enter a PC and find components for it, but I can't find it on their current-day website.

I have a Gateway DX4822-01 PC that's still nearly stock components save for 2 cooling fans put in afterwards. It's become inadequate and even gets laggy browsing the internet at times. A new PC or upgrading to Win10 isn't an option for me right now, I need to go in relatively cheap so I'll upgrade and keep this one going for a few more years. A new HDD and such aren't a trick, but I need to focus on 4 things-

* CPU
* RAM
* power supply
* video card

PC specs- Gateway DX4822-01 Specs - CNET
Motherboard specs- Acer EG43M Motherboard Specs

I still have the 6 GB of RAM, I can upgrade to 8GB max. I have the specs so this shouldn't be an issue finding a full 8GB set of RAM, provided current market stuff is fully backwards compatible.

PS will be next, aside from something more powerful to run a better video card, I also need something new in case this one fails from old age. So I need a recommendation on one to fit this case.

CPU, I don't need something new as of this year, I just need better & compatible. A few years old model would likely be much cheaper.

Video card... I want to run Skyrim on good settings, I'm not much concerned with newer stuff, so a semi-old model would be nice. HDMI maybe standard but I wouldn't mind VGA output too, as some older stuff I run tends to have odd issues with screen resolution stretching, of which the HDMI cable grays out certain monitor options that might fix that.

Realistically my budget is around $100-$125 total and being in the US my shopping options will mainly be Amazon, Newegg or eBay(if I go to the local PC parts shop their stock will be very limited and prices will be high- that's if they're even still in business, and I'm not pumping $20 into the gas tank to drive to another store the next state over).

I would trust MicroCenter more than Amazon, which uses tens of thousands of outside vendors. You can look up your computer's RAM at Crucial.com, then you can buy it from them, or find it cheaper elsewhere.

I ordered 8GB(4x2GB) of new Kingston brand RAM, and going by that chart above, the Intel Core 2 Duo E8600 was the best CPU upgrade option and was cheap enough used/tested. Total $37 after sales tax.

The PSU is priority over the video card for the time being and I'd vastly prefer to go new/unused on that one.

edit- found the Enermax ETK500AWT Tomahawk for $40, which is said to be compatible going by online searching. It's 500W. I also saw one by Dream PC that's compatible, but was only 400W. Now just to find a good 1GB video card that's compatible with this motherboard.

I don't think space is much of an issue, I have plenty for a longer card



The GTX 260 and ATI HD4890 cards can be found secondhand/refurbished on eBay cheap, but they only have DVI outputs for video. My current monitor is HDMI & VGA only, and while I can get an HDMI-DVI cable, I'd prefer to use VGA due to certain screen resolution settings that HDMI grays out in options. I don't really NEED to run Skyrim, I have enough games, but something better than the onboard Intel chip would be nice. I'll probably get a Geforce GT 610. I'm just not sure if I need 1 long or 2 short PCIE brackets for this case.

Cooling isn't a current issue. Speccy shows everything stays at a good 33-37C average at all times(maybe in the 40C range if I'm running games). I bought a rear case fan when I got the PC(it wasn't stock equipment!) and worked a separate front fan into the case later by drilling holes in the front case cover and bolting it onto the inner frame. But while the CPU fan is large it's also as old as the PC, I just need to find one compatible with this case to replace it, and unfortunately CPU fans aren't necessarily universal.

Some of my issues do require better hardware, unfortunately. One MMO I play is so badly coded that the load times are horrible and it's prone to lag & crashes, and while even modern hardware doesn't fix that, a better CPU and GPU would help to some degree.

Looking over the GTX 260 and ATI HD4890 better, I do fear maybe they're all too long to fit, they would come extremely close to the SATA ports even if they are just short enough. One card I got a measurement on is 9.5", which, after checking, would put it over the SATA plugs so it's far too long.
