Buy it if:
You want the most powerful GPU on the market.
If you are looking for the absolute best 4K graphics card for gaming or rendering workloads. It offers 4K resolution with high-frame rates and incredibly fast rendering speeds and will not become obsolete for a long time.
You have the power supply to handle the power requirement of a 450W power draw. Since this GPU feasts on energy, you’ll need a real juggernaut of a PSU to handle it. Your electric bill might even jump a bit after you buy this card!
You want to get the most out of new hardware standards, especially PCIe 4.0 motherboard slots. You would be leaving a lot of potential performance on the table if you were stuck with an older GPU while using such a nice motherboard. So, grab this card if the rest of your build is ready and able, with a PCIe 4.0 slot and plenty of free space.
Don’t buy it if…
You don’t already own a 4K monitor.
While the RTX 4090 can play games at either 1080p or 1440p resolution, it isn’t worth the money unless you play games in 4K resolution. You might look a little silly sticking with a raggedy old monitor while your PC is housing an RTX 4090. If you want to buy this card, upgrading your monitor should be on your to-do list.
You already have a high-end 3090 or 3090 Ti, as the performance gain doesn’t match the additional cost that the 4090 requires for purchase. If you just bought the high-end cards of the previous generation, you can comfortably sit this one out. Unless you like spending almost two thousand dollars to get some bragging rights, then it just isn’t worth it.
Lastly, don’t buy this card if the rest of your PC can’t handle it. In other words, if you don’t already have a high-end processor, a massive PC case, a new motherboard, and plenty of RAM, then this card won’t help much. The rest of your components will bottleneck the 4090 and hold it back.
So, make sure you have top-end components if you are eyeing an RTX 4090.
