Advice needed on upgrade/setup change

Guys I need your help please.

Current set up:

1. Mac Pro - 2008 2 X 2.8 Quad Core . 16 GB Ram 3GB HDs + 120 GB SSD

I run 3 monitors from this MacPro

2. MacBook Pro 2007 2.2 Core Duo 4 GB 120GB SSD


My use is general work nothing very intensive . Store a lot of photos, have a couple of excel spreadsheets that might be a bit intensive I also use Parallels on both machines.

My MacPro is occasionally shutting down and i have to restart it. Probably once a week. Occasionally it takes 3 or 4 attempts to restart.

My Macbook pro works great but is a little slow now but nothing noticeable for my use. I tend to use my MBP is different rooms and occasionally on trips.

I think it might be time to buy a new MacBook Pro 15 inch 2.3 Retina to use as my main machine. Thereby just having a MBP instead of the MP and the old MBP.

I assume i cant run 3 screens but can i run dual monitors from the MBP. I have to have dual monitors as i trade equities and need the ability for at least 2 screens.

Would you guys suggest that type of setup or would you advise something different.

I would greatly appreciate your thoughts.

 

I appreciate the reply.

I am running Mavericks but i dont think that is the issue .

I really love my MP so anything i can do try and remedy i will.

I saw suggestions here to another poster about dust. I cleaned as much as i could inside . Removed the ram and the HDs and dusted it down. It seems to be running well but the shut down could occur at any time.

I think it could be to do with the power management so as part of the clean i removed the power lead and let it sit for an hour or so.

I downloaded istat but to be honest i dont know what i am looking for.

The sensors seem to be running hot though. I am getting readings of 98 deg and 100 deg.All 4 HDs seem to be at 90 deg.

Any other diagnostics you can suggest i try ?

 

I think the fans are working ok. On istats the CPU fan is at 513 RPM.

So far so good today . Temp is constant at 99 deg.

I have the original discs . I will install and see what i can discover.

thank you again for the advice.

 

Thats an excellent idea. I hadnt given any thought to the Mac Mini at all.

For my requirements it could well be a great solution. As you say the drawback to using the rMBP would be the constant unplugging.

I cleaned my MP thoroughly inside and so far so good, i havent had an issue. I love my set up as it is and will probably buy a rMBP at some stage this year as my MBP is now 7 years old (although it looks and works like new).

Really appreciate the idea I hadnt even thought of the mini .

 

I actually haven't. . I will do so now though . Good idea. Thanks.

 

Guys i just wanted to post a brief update. Its been more than 2 months and i havent had a restart overheat problem.

It was definitely to do with some dust inside. It wasnt really visible but i got a compressed air spray and it did the trick.

Thanks for all the comments, they really helped and saved me a fortune !
