ngullies :
I am very tight on budget and i need a good cpu for renderings in AE and others. I have chosen i7700 kaby, though initially, it was i5 7500 with z270 but i need to sacrifice on one., so i chose the motherboard. Any suggestions as to why and why not my choice is good? full config will be - 2tb WD 7200rpm, 8gb ripjaws, 550watts corsair psu, corsair liquid cooling(~$60-100). I will be upgrading after a year ofcourse.Right now, its bare minimum for me, do something hat can keep me going for another 2 years will be good if any1 can suggest better alt. Thanks
If you don't already have any of the parts, consider instead going with an AMD Ryzen CPU - the only things you'll need to change are the motherboard and CPU, and you can remove that liquid cooler too, you won't need it even for the 7700. Another thing you would want to consider is fast RAM, as Ryzen processors benefit from fast RAM. Get at least 2666 MHz RAM, if not higher than that. Don't go over 3200 though, because most AM4 motherboards can't overclock RAM all that well.
So my recommendation for you would be this system:
CPU: Ryzen 7 1700/ Ryzen 5 1600 if you can't afford the extra cost(the 1600 would still annihilate the i7 in rendering)
CPU Cooler: Stock
Motherboard: MSI B350 Tomahawk
Memory: high speed 8 GB/16 GB kit from brand of choice
Storage: the one in the original post+ an SSD
Video Card: If you won't play games on the computer at all, get any cheapo graphics card, just because Ryzen doesn't have integrated graphics. If you do wish to play games, you'll have to mention a budget and your monitor config.
Case and power supply: Whatever you planned on going with initially.
The two Ryzen processors have more cores than the i7 7700, which helps you in getting much better rendering performance for lesser costs. Both CPUs come with a capable stock cooler, and the motherboard will allow you to overclock either CPU to a minimum of 3.6 GHz, most likely something in the 3.7-3.8 GHz range.
Due to differences in the architecture of the processors, Ryzen processors benefit from faster RAM, unlike Intel processors, which is why getting at least 2666 MHz RAM is recommended.
