How to downgrade BIOS?
Psu will function properly and the 4670k isn't 1.4jt where you're getting that number—this is one for 300rb. The i7 4770k seems to have dropped to about 600rb now, but it's still a questionable purchase when used Ryzen boards are available instead. Since new Z boards are expensive, I suggest a used Ryzen 1200 + B450 board; a used 1200 for 370rb and a used B450 Pro4 for 700rb. Save up for a Ryzen 5500/5600 later. For RAM, you can get a few 8GB sticks for around 180rb. You'll likely want Samsung M378A1G43EB1 or M378A1K43DB2, with Hynix options HMA41G6AFR8N and HMA81G6DJR8N. The former is better if you don't plan to upgrade beyond 16GB or want a Ryzen 5500. Just overclock the Ryzen 1200 to around 3200, bump it up to 3800 for the 5600, and aim for 4600+ on the 5500—though pushing it too high is tough to manage.
Apologies for the confusion regarding the price, I'll go ahead and purchase the 4670K right now.
A budget tower with 150-300mm height and 4-6 heatpipes works fine, but you can get more savings by adding a 775 copper core to the CPU. This is typically around 20mm and costs about 20rb on TokPED, though you should verify it’s a solid LGA 775 copper core rather than thin ones that don’t cool well. I can maintain temperatures near 85°C at 1.34v and 4.3ghz on my e8500 Prime95 mini-ft. However, on an H81 board you won’t be able to overclock much, so you’ll need to test BIOS crossflashing for OC support on H and B boards. I’ve already flashed a Z77M onto an H61M-D and a Z87M Plus onto an H81M-E, but I don’t have an unlocked chip to try further. So you’re likely stuck buying a Z board now. Given current prices, switching to Ryzen would be cheaper overall—especially if you plan to upgrade your CPU and motherboard later. The 2500k + P67 or P67Z68 combo is around 130rb now and can drop to under 300rb, but unless you’re doing serious cost-cutting, upgrading to Ryzen is the better choice.
