Can somone answer the questons I asked please? I really need to know.
Some of us have lives. Though I do not, so...
Oh I forgot to tell you what monitors I'm using!
Right now I'm using a samsung 300/350 as my main screen (24"). I'm playing games on this screen. The other screen is a weak Acer P205H (21"). I'll buy a new one later...
You should be able to run both monitors with a mid-high to high-end GPU with no problems (for most applications, but again, depending on what you want to do). If you find that 24-inch and 21-inch monitors setup is adequate, there is no reason to replace either monitor imho.
...If I understand you correctly, the best Mobo I can get right now for a gaming computer is an Intel Core i5-3570k. It's like the top right now on the market? Is there something better than that?...
Based on price, the best CPU or processor (not mobo, which is short for motherboard) per dollar for gaming is an Intel Core i5-3570K. I stated this in my previous post below.
...The Intel Core i5-3570K is the gaming CPU sweet spot right now. You can get a Core i7-3770K for about $100 more, but the gaming performance increase will be only be marginally better (though for applications the difference can be significant)...
Should you get the 3570K or the 3770K? Google "3570k vs 3770k" and do some research, look up prices and decide for yourself is the best answer I can offer.
...Do you have something else to suggest as a cooler? Those seem pretty cheap, no?...
That is the point. The Cooler Master Hyper 212 Plus/Evo is cheap, effective and appropriate for the typical enthusiast-level gaming build. What is it you want to do with this build though? If you want maximum overclockability and to be able to get the highest benchmarks possible out of a 3570K CPU, then yes the Hyper 212 is not for you. You will want a totally custom water cooling solution that might be half the cost of this entire rig. And in between the Hyper 212 and custom w/c, you can spend $75 - $125 on a high-end air cooling solution that will get you perhaps 5 degrees cooler at ambient. Imho, this scenario is a bit like the 3570K vs 3770K question - incremental performance increase for a lot more money. But that's for you to decide. Here are a couple high-end air coolers, but there are many more:Noctua NH-D14Phanteks PH-TC14PE
Incidentally, I think the above will cool about as well as the Corsair H100 All-In-One water cooler. I've read reviews that state the H100 is great, but I've read forum posts from users who don't give it that much credit.
...Am I better with a samsung RAM or the Corsair RAM I was suggesting in my own build (the corsair vengeance DDR3 1600MHz 16GB)?...
From all that I know to be in this world, that $250 Corsair RAM is a waste. Probably for any application, but I dunno. At least for gaming they are. From my knowledge, which really is not complete, gaming will benefit from RAM up to 1866 Mhz pretty much. Practically, you can buy decent 1600 Mhz rated RAM and overclock it, too. So what's the point of 2400 RAM I don't know. Maybe someone else can elaborate.
Do you have to get the Samsung RAM? No. The main issue with it methinks is that it's not particularly attractive. Almost any decent RAM will suffice actually. Imho, just don't spend too much or spend too little. 8 GB of decent 1333 or 1600 RAM will do for gaming.
...What is a SSD? Is it like an HHD? If so, what's the difference between a SSD and an HHD (maybe I'm just stupid and it's the same thing)?...
SSD = Solid State Drive
HDD = Hard Disk Drive
HDDs are older technology, mechanical storage devices that have moving parts. SSDs are newer tech with no moving parts. SSDs are much faster but more expensive. They are very useful for placing your OS and select programs and will give your PC some serious speed for boot up and those applications.
...Will I be fine with the PSU I have right now? I don't remember the brand, but I know it's 700 watts...
If it's this:http://www.thermaltakeusa.com/Product.a ... =1844#Tab0
...you should be fine. I would try to recycle it if at all possible. It could probably run any single GPU ou there right now, too.
...I also tried to find the ATI Radeon HD 5770 in the list and I couldn't find it. Does this mean that it's not compatible?...
Modern GPUs have no issues with compatibility with motherboards, as they are all PCI-Express (or I guess PCI) interface parts. PCI-E are standard interfaces in modern mobos.
Good job on pcpartpicker. That site rocks. Imho, you can keep the Corsair H100 - as long as you make sure it will fit okay in your yet to be selected case. Change the RAM though, as $250 is crazy. And definitely add a 128 GB SSD (256 GB if budget allows). Those are my thoughts. I'm certain some will agree and some will not
