Hello everyone, This is the first time that I’m trying to build a custom PC. I am gathering information about hardware for the past 10 days and I want your opinion because I am in dead end. First of all, my target is to build a desktop PC for extra demanding gaming, (lite to medium) multitasking and watching HD movies at high resolutions. Also I can tell that I am 99% certain that I will be using only 1 really good monitor. I want at first 8GB of RAM and I think of upgrading later to 16GB. Furthermore I am going for an ATX mobo because I believe XL-ATX is too much for me. At last I will NOT do any extra overclocking and I will stick to factory settings. If, in the end, I am going to buy something factory overclocked then I will not do anything more. As for money I am planning to spent at least 700$ and at most 1000$ (more or less). I am from Greece and the prices are from here in dollars. So let’s start with what I have so far... I with point my thoughts and I will explain after. 1) Processor: Intel Core i7-4820K 3.70/3,90GHz (CPU) 388$ 2) GPU: 1x Asus GeForce GTX760 2GB Direct CU II OC 317$ 3) Motherboard: ASUS P9x79 PRO 311$ 4) RAM: ??? (There are too many options) 5) PSU: Corsair RM Series RM750 80Plus Gold 162$ 6) HARD DRIVE: OCZ Vector Series SATA III 128GB 2.5'' SSD 152$ I can find these items at total price of 1352$ (It’s above my calculations but its ok) I want to believe that I can do the things that I mentioned above with less money, but I also know that "you get what you pay for". 1) Intel Core i7-4820K. I believe that it is pointless to have an APU and an extra more powerful high end GPU, and this is the cheapest of its category. I have also read in many forums about Intel Core i7-4770K, Intel Core i7-3770K, Intel Core i5-4670 but according to this http://www.cpubenchmark.net/high_end_cpus.html the i7-4820K has the best benchmarks of all and here the prices are almost similar (except i5-4670). Also If I was going only for games I would choose the i5-4670 because in games it is pointless to have HT and there aren't yet any games that can use fully 4 CPU cores. At last I came across with Intel Xeon E3-1230 V2 with really low price (221$) but I do not know if it is a good choice, because Xeon processors are mainly for server types PCs. 2) Thankfully this is the easiest part... It is Asus GeForce GTX760 2GB Direct CU II OC Or Asus GeForce GTX760 2GB Direct CU II 2nd choice Gigabyte GeForce GTX760 2GB WindForce 3X OC (rev. 2.0) I have almost made my mind because of the benchmarks in pairing with the prices. I also have seen Gigabyte GeForce GTX760 4GB WindForce 3X OC but I do not know if 4GB are more than I need. The difference in price is +90$ from above Asus (both same price) 3) Asus P9x79 PRO I have not found something better for the money I give. I know that if I am going with another CPU I am going also for another motherboard 5) Corsair RM Series RM750 80Plus Gold. I think that it is a really good deal for my system to run at its best 6) OCZ Vector Series SATA III 128GB 2.5'' SSD for system and programs (I am open to any suggestions). I am going to have a 2nd HDD only for storage. And I saved it for last.... 4) RAM!!! Too many compatibles too many brands I prefer 1600MHz over 1333MHz if the latency is better I am close to G.SKILL F3-12800CL7D-8GBRH(XMP) 8GB (2x4GB) 7-8-7-24 1,6V based on latency I want to think that eventually I will make a good investment!! Thanks for having to read all this and I will be waitting for your responses.
