How to choose a gaming PC on sale
A gaming PC deal is only good if the parts inside match the games you play. These are the specs and terms worth checking before you buy.
The graphics card matters most for games
For most games, the graphics card (GPU) does the heaviest work, so compare that first. Look at the exact model name, not just the brand: two GPUs with similar names can perform very differently. For laptops, the same GPU can be set to run at different power levels by each laptop maker, so two laptops with the same GPU name may not perform the same. Independent reviews that test real games are the best way to compare.
Then the processor, memory and storage
The processor (CPU) matters more for games that simulate a lot at once and for streaming while you play. Check how much memory (RAM) is installed and whether it can be upgraded later. For storage, an SSD loads games much faster than a hard drive, and modern games take up a lot of space, so check the capacity and whether there's room for a second drive.
Match the PC to your screen
The resolution and refresh rate of your monitor decide how much GPU you need. A system that runs well on a lower-resolution screen may struggle on a higher one. Check that the PC has the right video outputs for your monitor.
Don't overlook the power supply
Prebuilt desktops sometimes save money on the power supply. Look for its wattage and efficiency rating in the specs, and check the brand if it's listed. A good power supply keeps the system stable and gives you room to upgrade the GPU later. If the listing doesn't say, ask the seller or check the manufacturer's spec sheet.
Prebuilt, refurbished or open-box
A new prebuilt comes with a full warranty from the builder. Refurbished systems can cost less, but check who refurbished it (the maker or a third party), whether parts were replaced, and whether the specs listed match what ships. Open-box systems may have been returned for any reason, so check the return window and test it right away.
Read the warranty closely
Check how long the warranty lasts, whether it covers parts and labor, and whether you must ship the whole system back for repair. For desktops, some builders allow you to upgrade parts without voiding the warranty and some don't, so read their terms if you plan to upgrade.
Laptops: heat, noise and battery
Gaming laptops trade size for heat and fan noise, and most run on battery for much less time when gaming. Reviews that measure temperatures and noise are worth reading. Check the charger is included, since gaming laptops often need their own high-power charger.
