    WHY WAIT! BUY IT NOW! GREAT PRICE!

    WOW! for 400 bucks you cant beat this processor at this Price for an AMD upgrade, great for multitasking and Gaming! HUGE upgrade from the 3600x and you can use it on older boards like the x470 and it works great! HIGHLY RECOMMEND! Really this is a no brainer! If you get this you wont need to upgrade for years and let the new generation of processors coming out work out the bugs. In 3-5 years when the newer 7000 series matures and gets better all the prices will be stabalized and you will get the best of both worlds! Get this CPU before it is too late! You will LOVE it! Trust me. If you buy a 5600x that is ok too, but you will want to upgrade more than likely again in a year or two. Your next real upgrade path with AMD is going to be next Generation which will take a year or more to mature and prices to get reasonable. This processor will hook you up for as long as you need your next NEW BUILD! You can go 4-5 years with this untill your next upgrade with this processor for sure! This is the last of the processors coming out for the tested AM4 system and the best bang for top performance. Plus Best Buy Shipped SO FAST, 12 month financing no interest! Get IT!!!!

    An absolute POWERHOUSE!

    After needing an upgrade from my 3600x, I decided to go with this guy, and all I have to say is WOW! I had to COMPLETELY overhaul the components in my PC because of this guy- it's a powerhouse. Between a new MOBO, AIO, and even GPU- All so it wouldn't be bottlenecked by this beast of a CPU. It's a great processor if you're gaming/editing/streaming, though if you're purely gaming, the 5800x3D is a great option as well. TLDR- If you need an upgrade for gaming/editing/streaming, you won't be disappointed.

    AMD Finally Back On Top!

    AMD continues to impress. This CPU is amazing! The 5900X absolutely blows the Intel i9 10900k out of the water when it comes to productivity and can trade blows when it comes to gaming (something Intel generally excels at). It's so nice to finally see AMD competitive w/ Intel again. The Ryzen 5000 series processors are a big step up in architecture from the previous generation (3000 series), especially when it comes to gaming, better CCX efficiency, and improved IPC (instructions per cycle). The only con I can even think of is that these do tend to run rather hot, especially compared to Intel CPU's. Though it's not really a con since AMD has stated that it's expected that these can peak at 98°C without issue. Throwing on a decent cooling setup is highly recommended. I run an Arctic Freezer II 360mm AIO and temps generally range from roughly 37-38°C @ idle to 68-72°C @ load. Having said all that, this processor is in extremely high demand & will be very hard to come by @ retail prices. If you can eventually get your hands on one, even at a slight ~$50 mark-up from MSRP, I would still recommend buying it. You most definitely will not be disappointed with your purchase! =)
