Consider changing to an i3-12100f, though your current motherboard uses an LGA-775 socket (Gigabyte EP45-DS4).

The 12th generation is a completely different socket design.
Your current setup is outdated and won’t support future upgrades. You’ll need a completely new PC if you want to improve it.
You're significantly outdated, around 14 Intel CPU generations, and Intel usually updates socket designs every two years.
Upgrading to the latest Intel architecture or similar requires a fresh motherboard, RAM, possibly a cooler, and power supply. Depending on your current setup, you might also need updated storage solutions. I regret we didn’t provide a more detailed guide, but feel free to ask for assistance with configuring your new system.
You wonder if a dinosaur P45 board can fit a CPU from 15 years ago. The size of the new chip makes it impossible, but it’s still a decent board for its era—just useful only for overclocking a 775 as a hobby. Giga EP45 boards are top choices for boosting clock speeds on a 775, though UD3R or UD3P versions perform better. Prices have dropped a lot lately, especially with listings showing an EP45 paired with a Q8400 for just $10. DDR3 P45 boards remain popular for overclocking, offering no RAM speed limits and bigger capacities. They’re not selling well now, so you might be better off using them as decor or a secondary machine when upgrading. For a budget build with newer parts, consider a used B3/450 (around $50–70 for decent midrange boards) plus a Ryzen 5500, DDR4 chips around $30 for a 3200C16 kit, and even cheaper bare PCBs with 8GB sticks overclocked to 3800–4200. Just pick good RAM to avoid issues.
You can review my earlier post from March 9th to see additional parts, and my PSU is functioning well. Just my motherboard and CPU are the ones that feel old. 
Check the compatibility of your components. DDR2/3 RAM isn't suitable for an LGA1700 board—use DDR4/5 instead. Let me know about other parts like power supply, case, and storage so I can help you plan. A budget and country would also be useful for finding affordable options. What I see is an Intel Core 2 quad Q9550 GTX 1650.
He’s likely targeting the most affordable 12th-gen i3, suggesting limited funds. The key concern is setting a realistic budget. A Ryzen 4500 would fit well, paired with a basic B550 motherboard and a budget RAM bundle, keeping costs under $200. If that feels tight, consider refurbished setups with older components.
