Changing brand new stock pc into gaming rig?

NEW

mobo
ram 8gb

OLD
cpu - i7 860
mobo
ram 8gb

any graphics cards? power supplies? what motherboards?

Well then if you don't know what you've got, don't mess with it.

This is long winded, please bear with it and read to the end.
Great! The first pict. show the mother board: It is an ASUS (duh) F2A55-M/M11BB/DP_MB
The PSU is made by AcBel, they make a lot of Original Equipment Manufacture (OEM) psu's, and they aren't top of the line, but are o.k. It is marked 350 so they can market it as a 350watt unit, but in actuallity the sticker tells us that it is not: Combined wattage of the 3.3/5/12v rails is 286.4 (this is an important number) plus the -12V/+5Vsb (standby) of 13.6 for a total of 300watts. I am kinda sorry to see ASUS use such a low power psu in this system,but they have the engineers to actually calculate what the system needs.
It has two +12Volt rails with a maximum current of 13Ampere each which when combined usually results in something under 26amps. It is the current, not wattage, that is important (especially when choosing and adding a discrete video card).
That GTX 660 you are looking at requires a MINIMUM of 450watts for the entire system with a minimum of 24amps on the +12V rail(s) continuous power (not peaked or max) at 50C (internal temperature of the system and psu). That recommendation may be more then is actually needed but not by much; and if you were gaming would pretty much max out your psu.
(nice pictures BTW)
Ready for some more information? Here we go.
Your graphics uses some of the system memory (RAM) to run your games and, well, all graphics. According to your information it is using 822MB or your 8192MB (8GB) of RAM (more info. Contrary to marketing claims, 1GB is not 1000MB, but rather 1024MB; has to do with bytes and binary math which I am not into). IN addition, your motherboard is capable of running memory (RAM) in dual channel mode; this can produce better use of memory and faster reproduction of graphics and just about everything else. Your ASUS is ONLY using one channel: the stick of RAM in the first black slot (just right of the CPU) is an 8GB stick. You could probably improve the video and PC performance by adding another 8GB in the other black DIMM slot. HOWEVER, the two sticks of RAM must be perfectly matched or they won't play well together. It would take way to long to tell you all about RAM, so your best bet would be to pull that stick out, see who makes it and call them and have them match the specs.
BE ADVISED: BEFORE !! you even touch the RAM, shut down the computer, and unplug it from the wall/power source, then wait at least a minute for most of the residual electricity to drain out of the capacitors etc. THEN, before working with the RAM, touch a metal portion of your case or, say a nearby lamp, to drain any static electricity from YOU. Now, push down the white locks at each end and remove the RAM from the DIMM slot.
O.K., enough for now on all that.
Playing on a 55" tv: What resolution do you have your PC set on and your TV? The resolution I mentioned before is native to the 40+ inch TV that computer uses so you want to make certain your TV and graphics are set to the native resolution of the TV. ALSO, are you connecting to the TV with a VGA cable (blue connector) or an HDMI cable: it can make a difference.
Regarding crossfire: Yes, you need to use an AMD Radeon card with that APU,but let's deal with this later.Plus we're back to power issues again. And I believe, but I am not certain, that adding a different PSU will void your warranty. Let's deal with this later.
This will be the last thing for this response; you might want to call ASUS customer service and tell them the problem you are having. I have always had good results working with their people (some haven't) but they may have an answer.
It's very uncommon, but you might actually have a defective APU. I say this because I am getting marvelous (almost unbelievable)performance from my A4-6300 dual core, and your's should be even better.

I JUST NOTICED. Your system has NO intake fan for cooling, nor outlet/exhaust fan for cooling. Airflow into and out of the case is only provided by the PSU fan. I didn't ask before, but will now: ARE the lags and problems playing your games starting immediately upon loading and playing the game, or only after some time period -say 15-30minutes.

No game or payback, please. Don't think it is allowed here, and I have enough games already.
I do not have a Radeon graphics p.c. here at home so can't go into the Catalyst menu to look at settings, but there should be some good information available using a Google search. I know that AntiAliasing slows frame rates, but if you have already set everything superlow, then that is already turned off.
Just a side note: Your old pc, your parents, has a pretty powerful processor. It is a quad core, but the i7 uses Hyperthreading which allows them to act and perform as if it were an 8 core CPU. And Shoot! , that computer should have a pretty good video card in it! No wonder it performs so well.
I wouldn't worry about the little tape things you tore. I still think you need to talk to ASUS, especially if you find all the settings in Catalyst and still can't get it to play better.
How are you measuring your frames per second? Are you using FRAPS?
Another blurb: I have been working with another thread and did some research on the GTX 750Ti video card: It doesn't require the power of the 660 and runs pretty well, and would probably work in your PC (but not in crossfire). Here's a link:

"Im just going to buy the gpu and psu, and install them. What would problems would i run into?

You said the processor for my old pc is amazing, (2.80GHz [8CPUs]), but my new one is 3.7GHz(4 CPUs), how different are these numbers? If i had a 660 and the correct wattage psu, wouldnt it run fine? My old pc could run 2-3 games at once, which was nice, but very uneeded."


There is not time nor space to allow for any kind of discussion about Intel vs. AMD processors: That really is research you should do using old and recent articles in magazines and on-line that go into the History of processors, processor development in the last 10 years, etc. There are probably discussions here on Tom's forums and I know that there is a bunch of info in Tom's Archives.
"Ti" is a tradmark name of Nvidia's. It generally denotes a better performing video card within a specific numbered series ie. 750 and 750Ti. The 660 is not and does not have a Ti version. The 660 does, however, require an electrical connection with the PSU that your current PSU doesn't have, while the 750 does not.
You should be able to find tutorials, articles, or posts/threads, about 'how to install a video card' here on Tom's Hardware, and certainly using a Google search, and thinking back to the first time I did it I believe that the card will come with an instruction book. You will be changing graphics companies if you go with that Nvidia, so it is important, very important, that you disable and/or uninstall the Radeon driver etc. before installing the Nvidia card.
Which brings me to my final points; I will say it again.
"you might want to call ASUS customer service and tell them the problem you are having. I have always had good results working with their people (some haven't) but they may have an answer."
The work you are planning on will probably void your warranty. That means if something messes up you, or more likely your parents, will have to Pay for any repairs and/or replacement parts. As a parent I would be very unhappy and mad. They have gone to the expense of purchasing the computer for you; in my book - as a parent and grandparent - that's pretty cool. I really don't want to see you mess it up.
ASUS can tell you about the warranty and they may have a good idea of why your games play so poorly.

Best of luck!

You are doing a wonderful job explaining, good work. I just wanted to point out I have this card, and its a 660 ti

My Bad. I looked right at it on Nvidia's website and didn't even see it. Must have been too early in the morning. Thanks.
I did notice that the reference card takes two 6 pin PCI-E connectors.
iTriggz: there IS a 660Ti, my mistake.
